Random shut off 1996 sportster


New Member
Hello all,

I’m trying to diagnose a 1996 seadoo sportster. I replaced the magneto, dess post and rebuilt the carbs. After a couple mins of running it shuts off like an electrical issue. While it was running it would randomly cut out for half a second then resume running or just die. When i went to push the start button without removing the key it would beep once and when i put it back on i would get two beeps and it would fire back up.

The last time I took it out it shut off and when it came back on it sounded like it was missing and wouldn’t go more then a quarter throttle. Do you think this is a mpem issue?

Update: I replaced the mpem today with a known working one and the issue persists.

I appreciate your insight
