Two nights ago truck dies going down the road want start back everything comes on in cab no ignition no fuel pump nothing DEAD. Hour later it turns over no crank, haul it home put MODIS on has codes for all computer s and modem's clear codes and it fires right up. Next day cranks let it sit and run for 3 hours no problem. Next day drive it to church, after church dead again no ignition 8 hours later still dead. Help please.

Have to get back with you later code numbers have to hook it back up and read them again. Thanks for the interest
