We thought of that and changed it out with a new one. Still shuts down. One time it shut off when I was coming out of a loop on the down leg and throttled back. The prop was still turning and I turned the 42% onboard switch off and back on and it started right up. I have taken the 42% switch out and wired it straight in and it still shuts off when you throttle back to idle or bump the throttle up and down from the idle position. weard
