I'm helping troubleshoot an issue on my friends boat that he just picked up. It has twin 454's, 1984's. We ran the boat back about 200 miles and it ran perfect but randomly shutdown and immediately restart as if nothing happened. I have already swapped coils, no change. The coils, distributors, wires/cap rotor and ignition modules look brand new (Prestolite). I have an extra module I can swap next. I replaced the IGN switches already a well.
Do vintage '84 engines have the 50a resettable circuit breaker like my '88's do? I haven't looked too hard for it either but wondering if breakers have been standard Crusader equipment in general. This is on my suspect list along with the engine wiring harness connector and battery cables/engine ground. There is really no build up or stumble before the shutdown so I have pretty much ruled out fuel and because it starts right back up. Both engines get to around 4,200 no problem. It has mechanical fuel pumps.
What do you guys think? In the meantime, I never resolved my WOT issue but need to do that soon so I'm no carrying that issue into next year.
