Does it run good when it runs?
When it dies does it just shut off or does it spit, sputter and carry on?
When it starts does it start hard?
22re?

What stumps me is it will run fine and then bam dead I read something about the signal generator or whatever you call it in the distributor can over heat and stop work?.....

My old BMW was doing this exact same thing. I thought it was something clogging up the exhaust. It ended up being bad electrical connections/wires. Clean all of your contacts from the battery terminals, to the starter and ground especially. Also when this happens and the truck shuts down you can check all of your major wires for resistance using a multi meter. The wires were already bad and when they were getting hot, that builds up even more resistance until the voltage drops too low and it dies. When they cool down it allows enough voltage to let it run again

Is it cranking slow?

Try squirting fuel in the intake or starting fluid . If it fires it's the fuel pickup they are known to be clogged usually with rust .

sounds like a cam or crank sensor issue. cam sensor is in the distributor. if the sensor(s) or wires to sensors are faulty and expanding apart when hot the signal drops and the ecm doesnt know where the engine is according to firing order and shuts down.
