I have tallied the instances of the term "Lord" being used of Jesus throughout the canonical gospels, though I will also mention a few instances from some of the noncanonical gospels. The noncanonical gospels are often fragmentary, rendering a simple tally of instances something of a moot point, but sometimes one can perhaps glimpse overall trends.
For this tally I have excluded (A) quotations from scripture which include the term "Lord," whether I myself think that instance refers to Jesus or not, and (B) references to any character in a parable, whether (again) I myself think that instance refers to Jesus or not. I have also counted the few instances of the doubled up expression, "Lord, Lord," as only one instance of "Lord."
The instances I have included I have divided up into three categories: second person dialogue (a gospel character referring to Jesus as "Lord" in the second person), third person dialogue (a gospel character referring to Jesus as "Lord" in the third person), and narration (the narrator referring to Jesus as "Lord").

Other Gospels
The fragmentary gospel of Peter has 13 hits of Jesus being called "Lord," always in narration, and 0 hits of him being called Jesus!
The most common phrase in the gospel of Thomas is "Jesus said," and in only one instance does Jesus discuss his own lordship.
We find the following in the gospel of the Ebionites: "When the people had been baptized Jesus also came and was baptized by John. And, as he came up out of the water, the heavens were opened, and he saw the Holy Spirit in the form of a dove coming down and going into him. And there was a voice from heaven saying, 'You are my beloved Son; in you I am well pleased,' and again, 'Today I have begotten you.' And straightway a great light shone about the place, which John saw, and then he said, 'Who are you, Lord?' And again there was a voice from heaven toward him: 'This is my beloved Son, with whom I am well pleased.' And then John fell down toward him and said, 'I beg you, Lord, you baptize me.' But he forbade him, saying, 'Allow it, since thus it is proper for all things to be fulfilled.'" These are the only two instances of "Lord" in our extant fragments, both in second person dialogue; and besides the above instance of "Jesus" there is only one more in another fragment.
Of the four sure passages from the gospel of the Egyptians, three of them have Jesus being called "Lord" by the narrator (assuming Clement has not replaced something else with "the Lord"). The other calls him "Savior," again in narration. None of them calls him "Jesus."
We find the following in the gospel of the Hebrews: "The Lord, however, when he had given the shroud to the servant of the priest, went to James and appeared to him. James indeed had sworn that he would not eat bread from that hour when he had drunk the chalice of the Lord until he saw him risen from among those who sleep. .... 'Bear forth,' said the Lord, 'a table and bread.' He bore bread and blessed it, and broke it, and gave it to James the Just, and said to him, 'My brother, eat your bread, because the Son of Man has resurrected from among those who sleep.'" Two instances of "Lord" in narration. One other fragment of this gospel has him being called "Lord" in narration. There are other instances in which it is hard to tell where the quotation is actually starting.
The fragments of the gospel of the Nazoraeans give us two instances of "Lord" being used in narration. (Please note that I am not at all certain that the fragments of the gospels of the Nazoraeans, the Ebionites, and the Hebrews have been divided up correctly.)
The Egerton gospel fragments have two instances of Jesus being called "Lord" in narration.
The Berolinensis gospel fragments have two instances of Nathaniel calling Jesus "Lord" (and also "Rabbi") in second person dialogue.
The Oxyrhynchus 4009 gospel has one instance of Jesus being addressed as "Lord" in second person dialogue.
As a bonus, here are the raw data on the term "Savior" being used of Jesus:
Luke 2.11: 11 "...for today in the city of David there has been born for you a Savior, who is Christ the Lord."
John 4.42: 42 ...and they were saying to the woman, "It is no longer because of what you said that we believe, for we have heard for ourselves and know that this One is indeed the Savior of the world."
Noncanonical Gospels
Of the four sure passages from the gospel of the Egyptians, three of them have Jesus being called "Lord" by the narrator (assuming Clement has not replaced something else with "the Lord"). The other calls him "Savior," again in narration. None of them calls him "Jesus."
The Oxyrhynchus 840 gospel calls Jesus only "Savior" and nothing else (3 hits).
Discounting the noncanonical gospels for a moment, I find that Mark contains very little about Jesus being "Lord," much less than any of the other three: only 5 hits in total. Matthew is identical with Mark so far as the number of hits is concerned of Jesus being "Lord" in third person dialogue, but of course Matthew has Jesus being addressed as "Lord" many, many times in second person dialogue. How meaningful the second person dialogue category is, however, is up for debate, since other characters are also addressed as "lord" sometimes, this form of address being similar to "Sir" in English; the second person address is not always going to be making any kind of theological point. So Matthew gives us 21 hits in total. Next is Luke with 39 hits in total; what is remarkable about Luke is the 14 instances of "Lord" in narration. Finally, John has 45 hits in total, but fewer instances of "Lord" in narration (only 5) than Luke has.
The noncanonical gospels are more difficult to assess. The gospel of Thomas is at least a complete text; it shows less interest in Jesus being "Lord" even than Mark does. The gospel of Peter, on the other hand, never calls Jesus "Jesus," and habitually calls him "Lord." (I am sure one can imagine that this gospel was not about someone named Jesus at all, but I would have to see the arguments for that.) But the gospel of Peter is fragmentary, so who knows? The other gospels are also fragmentary, so it is hard to tell what may be going on with them, but it is at least interesting that, even among the sparse fragments of some of these gospel texts, it seems far easier to find Jesus being called "Lord" than it is in Mark or in Thomas.
As I have already intimated, I have several reasons for wanting to get these tallies on the table; time will tell whether they yield viable or usable results.
