I have a 1994 Chevy Truck that has been a super truck for me over the years. Well last night, my gauges started flickering back and forth, wind shield wipers started and wouldn't stop, and then the truck turned itself off. I could start it up again, but the gauges and wind shield wipers were still going crazy and the truck turned itself off again. This happened 3 or 4 times before I finally got home (about 1 mile of driving on an old country road).

Does anyone have any ideas what could be going on? Thanks for any help!
