Maybe you have a cat that sleeps under the hood, and is disconnecting the battery to use for its portable heater? No, well then I'd inspect the fusible links - if the clock is resetting, the whole shebang is going dead, so it is probably the main fusible link (I think that is the red one) that is intermittent. Funny that it doesn't let go when you are driving, though. Try wiggling that whole battery cable end of the harness with the lights (or some other item you will notice immediately) if it momentarily quits. The underhood light would be a good indicator too, if it works on your car.

When I get in the interior lights all come on and then everything goes out and the amp guage light glows very dim and eventually goes out. After waiting 10 to 30 seconds everyting comes back on and away I go!. Apparently it has been happening during the night as several times the last month I noticed the clock has started over again at 12:00 am. I have checked the battery cable connections and they are very tight. Any ideas? Leo H. '83 EFI with a poltergist
