I have a 92 Buick Century that, when the engine gets warm, just shuts down. No sputtering, doesn't overheat. Runs about 15 minutes. Wait 10 minutes and it starts. Runs smoothly. Fuel pump engages. Have replaced mass air sensor, ignition module and water control temperature sensor. When cooler outside it runs longer, but still shuts down. Help.

i have heard of similar isses with these vehicles for computer problems.

92 Buick Century 3.3 problem found . It took 2 tries, and 1 defective part,but the crank position sensor did the job. I was told that this is a big problem with GM products.Advice to others is try fuses then codes, the sensors. This was $600 headache.

what all was included in the 600 expense??

crank sensors will do it.
