2002 Expedition eddie bauer edition it's been having electrical issues for awhile, and just recently the alternator had to be replaced. Since then the lovely electrical issues have snowballed. Driving down the road, my locks start locking and unlocking themselves. Then the warning lights start going off (airbag, theft device, abs, battery). Then it starts to shake and I press the gas pedal, and nothing happen except it rolls forward slowly, like I'm idling through the light. I made it to the 7-11 parking lot just before it died. I've got no idea what is wrong, only that I'm either the owner of a very large paperweight, or my truck is possessed.
