I've had a "mechanic" look at it several times over the past few weeks and he found nothing... I got my uncle to look at it for two hours and he had the problem fixed. I am looking for a new mechanic.
-More to the point. It was apparently a worn spot on the engine ground. I really hadn't been able to get under the car to look at the wiring there.
I had checked everything that I could reach and knew how to, but, as you can see, electrical systems aren't really my area and I wanted a sound opinion.
-From now on, I'll stick to body/engine work
