You might want to take a closer look at that fusebox to make sure so it doesn't happen again. Check the wires that go to it from the battery and or the starter solenoid. Something is definitely loose. Better find it &fix it now before you get stranded somewhere.

 

So it did happen once agian. And I didnt basically the same thing. Just jiggled a few wires and power came back. So its definitely a short in wiring. However I have not quite pinpointed exactly which one it is. I am getting closer, to solving my mystery.

 

At least you know the general area the loose connection is. If it was a short, it would blow fuses or you'd smell burning wires.
