Spark fuel No Start

1995.5 2.7 5sp 4wd. While driving the other the the truck died and would not start. Towed it home swapped relays around checked fuses all were well. Pulled off the fuel line on the front of the rail and pulled the plugs. Seems to be plenty of fuel and good spark. Got in started right up. Let it idle for an hour took off and a block away it died and will not start again. Checked everything like before fuel and spark are good. Thought maybe bad gas but will not start on starting fluid either. Thoughts suggestions? Anyone had this issue before? OBDII shows no codes

 

My ignition switch went bad.......it would start cold.
and then drive for 1 to 5 miles and would just die going down the road..
it would pop the am2 fuse........

If I let if sit for about an hour.....it would go another 2 or 3 miles before dying and blowing am2 fuse again...Usually taking off from a stop light......

 

Interesting. I’ll check all the fuses again

 

Is it trying to start? Key in chiming? Or completely dead? Mine went dead at the shop after the alignment. Gave me a fright. Turned out it was just a loose battery cable that really didn’t look loose.

 

Cranks strong, good spark and seems to have plenty of fuel
