Sounds like no spark, may be a faulty coil or a crank or cam angle sensor, often when faulty when they heat up they can shut down and start working again when cool, look into this first.

IGNITION MODULES ARE NOTORIOUS FOR GOING BAD (DISTRIBUTOR MODULE)

EVEN BRAND NEW RIGHT OFF OF THE SHELF!

HAVE YOURS TESTED 5 TO 8 TIMES IN A ROW IF IT FAILS ONCE REPLACE IT

BEFORE YOU WALK OUT THE DOOR WITH THE NEW ONE. TURN RIGHT AROUND AND TEST IT TOO!

I'VE EVEN GONE AS FAR AS GOING TO ANOTHER STORE TO GET A DIFFERENT BRAND

INSURE YOU USE THE "HEAT SYNC GREASE" SMEARED ON THE BACK SIDE OF IT SO THAT THE HEAT WILL DISSIPATE THRU THE DISTRIBUTOR BODY

ANOTHER POSSIBILITY IS, WHILE IT IS RUNNING SORTA MOVE WIRES AROUND. ESPECIALLY AT THE DISTRIBUTOR AREA. YOU MAY HAVE A BROKEN WIRE, ESPECIALLY IF THEY ARE NOT BUNDLED AND TIES UP WELL AND WERE ALLOWED TO FLOP AROUND

ALSO. WHEN IT IS IN THE "NO START MODE". SHOOT A 2 SECOND BURST OF STARTER FLUID INTO THE THROTTLE BODY. IF IT STARTS OR EVEN ATTEMPTS TO START EVEN FOR SECONDS (BETTER THAN BEFORE)
MAYBE YOU HAVE A FUEL ISSUE. MAYBE THE FUEL PUMP IS NOT WORKING

LEMME KNOW IF ANY OF THIS HELPS
