Couple suggestions:
Underneath the air box bolted to the inner fender liner is a terminal stud for a power cable going from the battery to the Fuse Relay box in the cab. These studs corrode heavily and give you a high resistance connection. Pull the air box completely out and you'll see the heavy gauge wire that runs through a 1" square plastic cap. Pull the cap off and see how nasty that connection is.
While the truck is idling slap the underside of the driver side front wheel well, if it dies or stutters then it is most likely a wire connector. Check all the connections even if they look good.
Check the fuel inertia switch on the passenger side kick panel.
Pull the left hand front wheel fender splash panel, disconnect the ECM harness, clean the connections really good, then plug back in. You can test by tapping on it with a screw driver handle.
Good luck...
