If needed I can post the full sequence but this sounds like a flame sensor issue.
Sometimes the flame sensor gets dirty and does not heat up fast enough, cleaning it makes it work better.
option 2 is burner. the orifice can be dirty and need cleaning (Reduces gas flow and thus heat) or the air/fuel mix can be off a bit.
In my case.. it was the control board, but in yours, I think not.
