I have an 1987 olds 98 with the same problem. runs fine for about 15-20min. or until it gets hot and stalls. it will start back up after 5-10min. and run for awhile but repeats. i have replaced the oxygen sensor, wires and plugs, ignition coil and ignition control module. still doing the same thing. if i get it figured out i'll let you know and same with you please. i'm banging my head too. thanks grant in san diego 858.395.6058

Same answer! Crank position sensor.

Had the same thing with my 91 olds
Crank sensor!!!!

Theres 3 parts it could be if its electrical.
1. coil modules
2. spark control module
3. Crank Position sensor.
On mine I used a timing light to determine it was electrical first.

Hope this helps.
