Hello guys I have a yamaha 50 3 cyl i ran it today and it ran great for about 20 min. I slowed down from hitting a oyster bed and tilted it up, it cut off i cranked it back up and it would idle but when i put it in gear and gave it the gas it would cut off well i tried that a couple more times then it would'nt crank back up just turn over but not fire then in about 5-10 min. alarm went off. Any help plz!!
