I had this same problem with my Atwood/Wedgewood oven (OP has Suburban). They had a run of pilot burners that had the wrong size air mixing hole drilled in them.

I had to remove the fixed shelf that the burner/pilot assembly is mounted under to do the replacement. Problem solved now, oven works great!
Jim - when you say it was the wrong size, I take it that the hole on your original burner was too small ...?
I know it might be hard to tell from a photo but could you comment on the size of the hole in my photo compared with your original burner? Looks like I can make the hold smaller by adjusting the nut next to it but if it too small then nothing can be done other than replace it.
Actually the hole was too big. I did a temporary fix where I folded some aluminum foil so I had a strip several layers thick, about 1/4" wide and long enough to wrap around the tube where the hole is. By adjusting how much of the hole was covered, I could get the pilot burner to work and stay lit. The problem was adjusting it back there under that divider panel, and then keeping it there was not even close to an exact science. I would get it working only to have the foil move and back to no oven. You may want to try it just to see if that is the problem.
The symptom that I had was if I held down the oven knob and lit the pilot burner when all was cool in the oven, it would light and stay lit. When I heated up the oven and the main burner was on, all was well when the main burner flame was full, but as soon as it started to throttle back, the pilot burner would start to go out and relight with a "popping" sound. Once the main burner flame was low, the pilot burner would simply go out and then the main burner would shut down. I believe it shut down because the pilot burner was required to keep the thermocouple energized at that point, and when the main flame was full, it would keep lighting the pilot burner - hence the "popping" as it relit off of the main flame.
To be honest, I didn't see a lot of difference between the bad and good pilot burners when I had them both. I don't think I could tell either way from the picture, except yours looks just like the same pilot burner/thermocouple assembly.
Like I said, mine was an Atwood/Wedgewood. I don't know if your Suburban would have the same pilot burner. I just called the Customer Service dept. with the range serial number and got a replacement.
