Car stops on hot days 90+

92 La Sabre
Runs ok under 90 degrees
The car will runs if you are driving fast enough to keep whatever cool. If you stop long enough or shut it off it will not start for 15min or so. I do not think it is a crank sensor. It has spark when this happens :banghead:

It has spark but, does it have fuel?

What kind of shape are your coils in? They tend to fail at high temps as well as the crank.

Im am not sure but they tell me that it is not vapor lock because the fuel pump is in the gas tank and that is why they put them in the tank to stop vapor lock. I think at times that that is the problem????

When you say coils are you refering to the radiator?? It never over heats on the gauge but the next step I was going to do was have the cooling system flush out to help circulate the cooling system beter.
As far as the crank I shot it with cold freeze in a can and it did not help.

These are your coils: http://www.thejmfc.com/autos/delcoignition.html

If you have green-grey goo coming out, then they're shot. Otherwise, let the car run and at pitch black use a pair of well-insulated pliers to pull each plug wire end off each post. Check to see if the engine idle changes (if it does, it is good, if not, then I'd say that coil is bad) or for erratic spark.
