if the voltage regulator is starting to intermittantly go it can cause strange problems like this. i had a ford close to the same thing would happen to. tested fine at all stores taken to but would spike and drop voltage on its own. grabbed a junkyard unit for like 15-20 bucks and swapped it in. worked fine after that.
