I have a Mercury 150 EFI 2 stroke on my 1995 ProCraft. For the past year, it has been intermittently shutting off while getting on plane. I thought it was a fuel problem, but recently I found out that if I trim the motor down after it shuts off, the motor then turns right back on. In fact, if I hold the trim button down, the motor stays on. Now I’m thinking it is an electrical issue, but I don’t know what it could be.
