If I let the truck idel for 10 to15 minutes it will stall. You can drive short distances butt if you drive to far the engine stalls pull off road wait a few minutes starts fine few miles stalls again. Have replaced alternator belts plugs wires rotar all new msd products.I have two small children and so I dont drive truck with them. Can you advise maybe fuel pump filter and blow out fuel lines or do fuel pressure check?

Next time it stalls do below immediately don't wait for nothing to determine if its fuel or spark problem and come back with some results

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
