It has only happened twice since I've had the motor. It starts and warms up perfectly. The boat jumps on plane for about a minute, then the engine shuts down. No sensors go off. It just won't turn over. After getting back on the trailer and waiting awhile I tried it and it started off and was great the remainder of the day. I have never run ethanol in the motor and use an additive also. This has happened twice this year first time was 4 months ago. I fish at least twice a week and this motor has been amazing. Any ideas?
