At full throttle and at other speeds, the engine cuts off. When this happens, I put the shifter in neutral, turn the key and the engine starts right back and runs for a while before cutting off again. During my last outing, I ran the engine approx. an hour and it cut off twice at full throttle and once at approx. 4000 RPM during the one hour time period. The bulb stays pumped up.
