This may be a crankshaft sensor. It will be intermediate and will not show a code. It may also be the the Engine Control Module and/or the Mass Air Flow Sensor. I speak from experience.
I had a similar problem with my 1992 Buick Park Avenue - it would cut out while driving - After replacing alot of sensors, maf, and coils etc - which did nothing - i found the problem was with the crankshaft position sensor - this is about $22 at autozone - not too hard to replace. Now no problems with cutting out at all. It could also be the timing belt. If the timing belt fails the engine will stop running and the car will not restart until it is replaced. TommyTrouble
I have a '92 PA that would die after it warms up. I had to have the crank sensor replaced and later had the cam sensor replaced. Either of these sensors can cause this problem. The computer needs both of these signals to send the fire signal to the correct spark plug. The old distributor used to do this function. Having the error code read out will tell you if this is the problem.
I had a similar problem with my Mazda 626. The car will completely stall while driving and can not be started again except after few minutes.It turned out to be my distributor electronic ignition component gets overheated and stop functioning.When it cools off it starts again. Replacing the distributor solve the problem.
