They may not be coming loose. It could be that you have water in one or several connections. You could also have a rub through somewhere that grounds out when wet or when the machine vibrates it to ground.

I hate electrical problems.

I would start by disconnecting the connections one at a time and blowing them dry and the hitting them with an electrical contact cleaner before hooking them back up. While doing this keep a lookout for rub throughs.
