Driving on freeway, engine sputter, press gas continue to run. Stop for about 4 hours, start engine..goes about 4 miles, engine sputters and shut down. coast to side of road, turn key restart then shut down. towed to home, start engine. Engine runs for about 15 minutes then shutter and shut down. wait about 15 minutes engine will restart and repeat. try driving but load seems to decrease run time. At high idle, engine rock back and fro...then sputters small pop and shut down. I've change the fuel filter, fuel pressure regulator, and think that I've checked the fuel pump relay. Turn key fuel pump engage. What is the problem and how do I fix it. Thank you.

Check the fuel pressure to rule out a dying fuel pump
