wont restart on 1991 Buick Riviera

Car has new fuel pump, new ignition module, & new battery. Before module, car would die while driven. After new battery put in, ran for an hour then would not restart. restarts when cools off.

Hi, try a fully charged battery....start the car....and check the "alternator" to see if it putting out enough voltage. An alternator puts voltage back in the battery while you're driving and a "wee bit more", however, a low battery "might" not get enough juice/voltage to restart the car. So you end up "jumping" it from other cars, or having the battery "recharged" just to get home! NOTE: a slow-"trickle-charge" over a long period will be safer-better to helping restore a depleted battery. - callhow

New battery. Sadness.
