Could be any number of electronic sensors ,engine management systems componets etc..... Having a professional repair shop hook up a factory or professional scanner to view engine sensor data parameters is what you should do .

Without testing we'd only be guessing . You wouldn't want to replace a bunch of parts you don't need ,would you ?

There could be many things to cause this problem.
Ideally when it quits is the best time to begin the diagnosis. First thing is to check to see if there is spark at the spark plugs when cranking and listen to hear the fuel pump run when you first cycle the ignition on.
But going on experience and what you have told me so far I would begin with ignition problems.
Because you mentioned it quit while driving and restarted after a cool off period it makes me think that an ignition part is failing when hot.
Engine heat and electrical current flow can heat electrical circuits, expand them, and go open circuit.
An ignition module, the pickup in the distributor or the ignition coil would be on my first checklist.
Give me a note back if you need more leads.

Hi,I just replaced mine.It is not that hard.just buy a manual on it at autozone,and it gives the specifications and step by step directions to dissassemble,and reassemble.I put in new plugs,thermostat,and flushed the motor for around $200.00.runs great!
