1992 Honda Accord

MY CAR RUNS GREAT THE ONLY PROBLEM IVE BEEN HAVING IS WHEN AFTER DRIVING FOR A DISTANCE THE ENGINE SHUTS OFF WITHOUT WARNING JUST TURNS OFF SO I WAIT AWHILE A FEW MINUTES AND IT TURNS BACK ON AND THE SAMETHING HAPPENS OVER AND OVER AGAIN, THE POWER STAYS ON WITH NO PROBLEM. ITS GOT A NEW BATTARY, WATER PUMP, IGNITION COIL, STARTER, SPARK PLUGS, GAS FILTER, OIL FILTER AND AND OIL CHANGE, IT SEAMS TO BE HAPPENING MORE FREQUENTLY. I WAS TOLD IT COULD BE THE ENGINE MODULE. I DONT KNOW WHAT THAT IS. WHAT COULD BE WRONG WITH MY CAR.
