Bake burner turns off and can not reignite

The cooktop and broiler burners work. The bake igniter will spark and ignite the bake burner. The temp will slowly increase to preheat, often reaching the designated temperature in a reasonable amount of time. Then, the clicks of the ignitor will be heard again and no re-ignition of the flame will be heard or seen. Am I correct in thinking it is the DSI module that needs replacing?
