The next morning after using the remote to unlock the trunk before getting in the car, the car would not start. I mention the gas and the trunk release because those are the only things that happened between the car working and not working. Here were the symptoms:
1) The starter would crank strong (so the battery was fine).
2) No other electrical components worked (lights, radio, blower motor, power locks etc.)
3) With the ignition off some of the red idiot lights would glow dimly on the dash.
4) If you try to turn the lights on, something would click under the hood.
5) The gas gauge had gone all the way past full and was pointing downward.
6) When you would pull the BTN fuse in and out from the fuse block under the hood, you woud hear a bunch of clicking under the hood. The same thing happened with the ROOM fuse from the fuse block inside the car.
I checked everything I could of thinking that maybe something had crossed under the fuse box, or maybe a wire was grounding somewhere. The car was towed and as soon as it was dropped off the truck, it started and everything went back to normal. A few seconds later it cut out and went back to the above symptoms. I had a mechanic check things over and after his pulling and prodding they found nothing but the car started and has been working fine for the past couple of weeks. The only strange thing that happened twice was that for a few seconds while driving, you would hear a click and the electrical components would die (blower motor, lights etc.) and the red idiot lights would flash on and then it would go back to normal. This all occured without any engine power loss. As you might imagine I am completely stumped and am starting to worry about the reliability of the car. If anyone has any ideas I would greatly appreciate it. Thanks.

Beckery1,
When this power failure occured, everything was inoperative except the starter motor/relay....If this is a correct summary, the problem lies between the battery (+) terminal and the Main Fuse (60 -100 Amp) located in the engine compartment. Check the fuse, check for bad connection, broken wire, loose bulkhead connector, etc.
Rational: The Main Fuse controls all circuits EXCEPT Starter Motor/Relay. If this circuit were "open" nothing would work except the starter, and those were the symptoms. Poor contact is causing the intermittent condition.
