200 HP Ocean Pro - just quit running

[mrlmd1]

I have a rebuilt mid 90's 2 stroke 200 HP Ocean Pro on a boat I recently bought. As soon as I got it, I changed the plugs and the lower unit oil. The fuel tank has ethanol-free gas in it that I mixed with the proper amount of oil (oil injection has been removed). It starts instantly, ran well the last time I used it a week ago, started instantly today, ran it at varying speeds (still getting used to it and the boat), up to 4500 rpm for 5+ min, slow/idle speed for 10 min, pisses water fine, ran smooth with no problems. As I was maneuvering to get it on my boat lift, at idle speed in reverse, it just quit and would not start again. It cranks over, just won't cough, fire up, or run. The fuel line priming pump bulb felt soft so I pumped it up until firm again, but it still won't fire up. I don't think I flooded it, the sudden stopping sounds to me more like an electrical issue, like something disconnected or suddenly failed. Any idea where to start looking or checking? Could be in the throttle/ shift control, coil, or ???????
At least it crapped out 20-30' from my dock instead of miles offshore.

OK, so now 2 hours later after letting it sit, pumping up the priming bulb again, after 4-5 times trying, it started and runs fine, not missing a beat.
Any ideas about what caused it to quit to begin with? I hate when that happens, an intermittent problem, you never know when it's going to pop up again and it's harder to find.
Does this motor have one coil, or 6, one for each cylinder? It's possible for a coil to show failure when it gets heated up.
And the water gauge on the dash, measures from 0-30. Is that psi?, doesn't look like a temp gauge.
Thanks for any input.

Powerpacks have a known issue with intermitten problems. There are 6 coils, not likely all go bad at one time. Best thing to do is if it happens again check for spark. If no spark check your kill switchs (neutral and safety).
