Help, 1988 Starcraft Islander, Merc 4.3L, Thunderbolt Ignition.
Boat runs fine for short time then dies, turn the key nothing, no click dead, lights out, 30 seconds later runs fine then repeats.
So far I've found that I loose power to the purple wire going to the coil, this is the key switch wire, I'm going a try new switch, I think next, I replaced the coil and this did fix it. I've wiggled evey wire and terminal and can't fine any thing after awile the problem is gone until next time i use the boat. I also noted i had power to the 60 amp CB while no power to the Starter small solenoid.
Funny thing is after the boat died I watched my panel light on for 5 seconds then off for 5 seconds repeating itself like on a timer, but don't stay broke long enough to fine a problem. Any ideas?
mean while i'll get my color penciles out and study my diagrams.
Thank you

I found No power out of circut breaker on the switch panel, after removing 6 screw and pulling the panel out, I quickly pulled the bildge pump wire off its breaker and reconected the spade connector that feeds the ignition wire to the key switch and i was up and running as the frieghter passed by me a few hundred feet away! I was happy it failed long enough to trouble shoot the issue, but kinda scarey how it happened!
