Ok was driving home from a fishing trip, boat and trailer in tow when my truck died at 60 mph.Complete loss of power, RPM dropped to zero and all guages showed as if they would when first started. Fuel pump and relay all seem to function as in I can here the click and initial whir of the start up process but to no avail the engine would not start. chocked and sputtered but would never start. let it cool and even open the gas cap to make sure there wasn't a vacuum lock and never could get to start. long and short of it was had it towed to my house, left it overnight with charger on the battery (drained it trying to start) low and behold it fired right up this morning. Any ideas?? No CEL 99 F150 4X4 5.4L 84000 miles
