My last trip out my boat decided it wanted to have a fit. We launched the boat late in evening and cruised up river for dinner and the boat ran fine with no issue. After dinner I plugged in the light and headed back to camp. Within 5 min of running the boat die, and I lost all electrical no lights, ignition, blower nothing. I checked all the connections I could with the limited amount of light from cell phones, and did not find any loose connections. After being towed back, and boat on the trailer, I checked everting the next morning and still could not find anything. For shits and giggles I tried starting the boat and it fired right up. So then I pulled the boat to the ramp tried to fire, and nothing. Same a the night before no lights, blower or anything. So I sat and scratched my head for a sec. then tried firing again and she fired. I let the boat run for a couple minutes to see if it would turn off, but noting happened. Didn't want to risk having it shut off on me again we didn't run the boat for the rest of the weekend. Has anyone ever experience something this? I've searched this site and others and really didn't see anything with same situation. Just to be clear batteries are charged and good, ground wires are tight, all wires under dash are tight. No burned wires anywhere that I can see. I'm at a loss.

Have I pulled the alternator and tested it... no.
Would a bad alternator allow the engine to start?

I'm thinking it's the key switch.
Check the connections under the dash.
Do you have a perko switch? Look there too.
Somewhere the main power feed has a bad connection. Start at the battery and work forward to the dash.
Don't forget all the grounds, too.
So, Ford Chevy or Olds? And what distributor? Carry a length of wire, with the right ends, to be able to hot wired it if need be.

Alternator could have a charging issue that will not keep up with your battery usage yes it will start if the alternator is not connected I had one that did that come to find out one of the wires was loose and it was intermittently charging

Pretty easy check though if you can get it to start disconnect the battery and see if it dies also pretty easy to pull it out run it to the part store and have them check it alternators can be funky at times

Mine recently did that same thing. Didn't die while running, just wouldn't start , then would start.
I think it's my solenoid on the starter. I'm going to set up an auxiliary solenoid system. Right now my battery and alternator go to the starter solenoid. If it goes bad, I think I'll lose all power.
