There is a check valve in the fuel pressure regulator that maintains fuel rail pressure when the engine is not running. Check it first before going after a leaky injector.

seek and thou shall find ,but first remove sender unit in fuel tank and drain gas from it then connect a 12v supply direct to pump and see if it works

I'd check the manual transfer valve on the dash. They have a tendency to go bad after awhile. Cause 1000 different symptoms, and be the last thing checked/replaced. It's probably the cheapest place to start. The pump under the driver's feet is usually the last one to go in my experience, but the secondary culprit is normally the main pump in the rear tank.
Next time it tries to stall, toggle the fuel switch and see what happens. Same with a hard start. Back and forth a few times quickly.
Hope this helps.
Testimonial: "thanks for the tip. Already replace this switch. "

It sounds like you might have a clogged catalatic converter on the exhaust system.
SOURCE: how to change a fuel filter on a 95 ford f-350
You will need to check inside the frame under the drivers door for the fuel filter. You will need a tool to remove the fuel lines. Remove clips from the fuel line holding the fuel filter (new ones supplied with new filter). Use the tool to insert into the fuel line to remove on both sides. Once lines are removed, remove fuel filter and replace with new ones. Be sure to put in new clips and attach lines. Good luck

first hit the fuel tank with rubber mallet where you might think the pump is. it's best to do this with someone trying to start the truck. if the pump comes on, it is definitely the pump. you can also check at the relay look at the relay and it should show a diagrahm. jump the leads with the switch, not the coil, first check your fuses and check for power at the relay
