When the oven is turned on, the igniter glows as it should and then the gas comes on and the burner ignites. A short time later the burner turns off. Then the igniter comes on again and the oven restarts with a larger than normal “poof” as the burner comes back on. (This is the burner at the bottom of the oven). My suspicion is the system isn’t recognizing that the burner has ignited.
