Hi s and welcome, It don't sound like you have an ignition problem, you say the burner is coming on. I'd lean more to a flame sensor. These can be cleaned using steel wool. Good luck

Hi there, May want to also check limit controls, That may be the safety control that is tripping out. Hopefully this will help you out .
