'84 dies on hard acceleration, restarts

Hi.

Started having an unusal problem. My '84 Carrera dies on hard acceleration (instantantly, as if you turned off the car). If I push in the cluth for a a few seconds the red engine status lights will come on, and I can pop the clutch and it will restart fine.

A few times, I had to push in the clutch again (twice) in order to get it to restart. But it has never failed to restart. (Knock on wood.)

Items which may help troubleshoot:

1. Car has 170K miles, original engine, never rebuilt.

2. Has never died in 1st gear. The higher gears seem more prone.

3. Seems to die more on the freeway (in higher gears).

4. Seems to die going *up* hills more (more acceleration going up a hill).

5. Car starts fine, especially cold. Warm/hot starts are not so instantaneous.

This problem is unsettling, as you might imagine.

Any ideas what might be causing it?

Is there a chance it might be the DME relay?

clogged gas tank? Pinched fuel line allowing only partial fuel delivery? When was the fuel filter last changed?

the fuel filter has not been changed in some time. Tho I didn't think that would kill it so suddenly. I thought, if the fuel filter were clogged, it would simply run rough during acceleration. You think it could be the fuel filter?

How do I check the overboost switch? What does that do?
