Don't look any farther than the wiring for the cause. Water and heat would (IMHO) :lol: :lol: in no way be able to be so sudden, total and intermittant. Check the contact of all the fuses, (pull them out and put them in, same with the battery cables. For me, I would stop at that point and wait for a replay, and take my 10 mm Allen at all times. Next time it stops, tilt the tank and start wiggling all the plugs. The dealer will be really handicapped by the intermittant nature of the problem. Good luck. This can be the worst thing to try to track down. (No pressure washing for me, :cry: )
