Whirlpool gas range will not heat or broil

Oven stopped heating and broiler doesn’t light, the burners work fine. When I press the start button I hear the gas start but a couple clicks later I hear it stop. The time continues to countdown for the preheat but there is no heat or sound coming from the oven. Not sure if it matters but this happened after the oven was preheated to temp. The burner failed to relight to maintain oven temp.
