Car was running great until the engine just shut down while driving
I had the same thing happen on a 91 Olds 88. Replaced crank shaft position sensor, coil, and ignition module. That solved the problem. I think the culprit was the CSP Sensor, but changed all three so can't say for sure.
The problem seems like a faulty ignition module under the coil pack. The reason it quits when hot and starts after it cools is related to the coils getting the module to hot. The coil pack will misfire as not all coils need to fire to run.
I replaced the csp sensor and coil but not ignition module

Driving along and the car just stalls! Wait a lil bit and it will start up again! Now after a month of this happening it wont start at all
car just quits sometimes while driving or starts missing and running rough like it wants to quit then sometimes it runs perfect i have changed the coil,spark plugs and wires,mass air flow sensor and the intake sensor when running rough engine light does not come on
check the fuel pressure, check for spark.
