if you have a ground that is even the SLIGHTEST bit loose I would start there. IF the power and ground connections are not tight enough that you can move/wiggle them then they are not tight enough. Electronics does some funny stuff when it has almost but not really kind of sorta enough voltage or current and that could be your problem.
I'm going to start with the battery and negative cable. I'm desperately hoping this is the issue... since the battery has full voltage and the engine box has about half, and the interior box has almost none, there seems to be a problem getting power from battery to fuse boxes.
