Pull the lower front panel and inspect the top of the burner. If there are ashes and debris on top of the burner, especially near the ignitor, then clean it off.
Also, there is an inline thermal fuse located below and behind the gas valve. It looks like a thick black wire covered with shrink wrap, with a spade connector on each end. Try pulling it and temporarily bypassing it with a jumper wire. If this solves the problem, then time to go get a new thermal fuse.
