SRNA3BBE Surburban range + oven

I was reading an earlier posts about the surburban SRNA3BBE range/oven combo and I have the same problem as described. The pilot by it's self operates perfectly. (let it go over night, just fine so I'm assuming the thermocouple is not the culprit). It fires up the oven as it should and when the oven get's up to temp and the burner cranks its self back the pilot begins to sputter and then it all eventually goes out.
Can any of you offer a potential solution?
thanks for any assistance or suggestions.
