After driving for a while 20 miles or so, the truck stalls as though it ran out of gas or lost spark. After setting for a while, it will start back up and drive fine.
I have replaced dist-cap and rotor, plug wires are new, I can hear the fuel pumps when I turn the key, the turck has duel tanks. I have tried switching tanks when problem ocurrs, no good. The truck has over 100,00 on it.
What should I try next?

Your going to have to test for spark at the plug and correct fuel pressure at the time it is dead. Once we know that, we'll narrow it down.

Thank you ASE Master Technician, the problem turned out to be the coil. A five minute job to change. Good for another 100,000 .
