Car power suddenly cuts out and in again.

1990 Geo Tracker, 122,000 miles, electronic control box changed out four years ago. The car has been sitting for two weeks, started up like a champ.

I'm driving down the highway at 72 mph and all electrical power suddenly cuts out and the engine stops running. I change lanes while coasting and heard a faint beeping noise coming from around the glove box (like a thermal warning?). I pull over and as soon as I tap the brakes and touch the ribbed shoulder the power cuts back in, the radio is even on the same station like nothing happened. I drove another 25 miles without incident. It was dry out, no rain or snow.

Short?

Thermal overload of something?

I did not notice any funny sounds before the power cut out.

Ideas and suggestions of what to look for.
