Atwood range

I have a Atwood range in my TT and while camping this past week. I was using the oven, it lit fine and warmed up the oven. I had it set to 425 degrees. While the food in the oven was cooking, I heard a popping sound coming from the oven. I looked in the oven and notice the main burner was going out and relighting off and on. I turned the oven off after noticing that. Has anyone had this problem before that could offer a quick fix? Thanks!
