My wits end...
I have been having this same problem for a long time and in my 95 F-150 4x4 w/ 302. It dies at stop sign or anytime I stop. And when I attempt to pull out it will completely cutout and mis like crazy then pick up and go on IF it doesn't die again. Here's what I've done. Had a bad O2 sensor and replaced it. Replaced throttle pos. sensor, pcv and hose, idle air control valve, ignition coil and module, stator, plugs, cap and button. Wires and ran 2 bottles of injector cleaner through it. A new fule filter. I have 32 psi on the rail with 36 under load. I blocked off the EGR with hi temp. gasket material to see if it was stuck open but still the same result. No codes are showing according to Advance auto. I can't find any vacuum leaks. What's next? Thanks, David.

EDIT. Knowing that a fuel problem is usually a more sluggish miss and an electrical one is more sharp and harder, I feel you are dead on with this diagnosis. If so, I'll put your name in my sig forever. Thanks quicklook.

The keyed lock/tumbler is where the key goes in. Remove cowling around collumn and use a small stiff wire to stick in hole to release tumbler. Must have key in it.
The actual ignition switch is near the pedal assy's on the collumn itself with a rod running up the collumn to the key stuff. Cheap and easy but I doubt if it is the culprit.
More likely things:
Vacum leak. Doesn't take much of a leak to make truck act like you describe.
One or more sensors in the air intake between filter and manifold are dirty, broke or unconnected. Would show a CEL code though.
