My father has a 1994 Olds 98, 130,000 miles. It just started this problem. While driving along, it just dies, no electric power at all, no windows, locks etc. After a few minutes it starts runs fine. Just before dying, it starts missing badly, then seconds later it dies. Olds dealer has hooked to the computer, and $130 later, could not find any problems. Sounds like something getting hot then resetting after cooling for a few minutes. Has anyone else experienced this?
