On my way to Atlanta the other day, the van ran great...except for one small problem.
I completely lost all power for a split second three times while driving down the interstate. I lost lights, radio, and spark. It came back so fast that I didn't believe it at first, but then did it again. I hasn't done it since.
What would cause this? The only thing I can think of is the negative terminal coming loose, but I checked it and It's tight. Anything else that could cause it other than a loose battery terminal?
