Default Friend Needs Help Please.

OK, PROBLEM IS friend has a 90 with a newly rebuilt 350, all stock. once in a while his car will just die out as if he shut key off. after a minute or so it will start up and run fine for a while. he brought it to a garage to get electrical system checked out and they said it was fine. he went back because he still had problem and they checked for codes but nothing there. they sais he should leave car with them and they will put it on a machine running to see if they can make it happen. anyone have an idea what it could be? i think they said it may be the throttle valve or something like that, thanks in advance, nutsy.

Could be the idle air control valve, but the symptoms don't seem to be a perfect match to me. Maybe someone else will chime in...

I would check the grounds, there are several on the rear of the engine were the transmission bolts to the engine, make sure they are tight, clean, and making good contact.

I'll 2nd the grounds or maybe the ignition control module if it's a heat related shutdown issue.
