92 Buick Park Avenue stalling

92 Buick Park Avenue, 122k miles. Car starts fine but after it reaches operating temp, the engine sometimes just dies, no lurching, bucking, etc. It just shuts off. A few times I've been able to start it up immediately but most often I have to wait 10-20 minutes before it will start again. It cranks but won't start. I've replaced the ignition coils and had the ignition module checked out (okay supposedly).

Any ideas on what to try next?

Thanks for any help.

Bill

you need to check for spark while it wont start if it has spark then you can check fuel pressure and injector pulse but you need to find out what the car is losing when it dies.
if its losing spark the crank sensor or ignition module could be bad the ignition module may test good and can be bad intermitantly. crank sensor failure is much more common than module failure.
