We put in the water this weekend and everything was working, barely got a few hundred feet from the dock and the pumps went out again. I tried tracing all wiring I could get to and couldn't find any reason for the short. I pulled on the hot and ground on the circuit breaker in the engine bay and felt a tiny bit of play on the hot wire. I tightened the hot wire nut, maybe a half a turn and it was tight. Pumps work and didn't have a problem all weekend.

I'm just posting this in case somebody else has this type of problem. Crazy the things electricity can do.
