Did you recently work on something to disturb the fuel lines, fuel filter, injectors?
Wet ground under truck?
(Under fuel tank straps, top edge of tank where all the salt and debris sits)
Fuel lines rusting out?
(look for wet lines)
Truck running poorly?
(Fuel Pressure Regulator, pressure test it!)

i posted a thing a while back and people said i have a fuel pressere leak. no wet lines. It turns over for 10 or 15 seconds when it hasnt been ran for a while. it doesnt matter if it is warm or cold out its always the same. once started if you shut it off and restart it is fine. there is a box back by the spare tire that looks like it has a little wet spot but i havnt touched it to see if it smells like gas. but ive had about 5 fuel filters on it. the last one i took off the gas was like a blackish brown color.

Kill em all
There is a valve built into the fuel pump that keep the system primed all the way to the injectors. Do this, but very carefully. Press on the Schrader valve on the fuel rail, have somebody turn the key over. Keep turning the key over until it squirts fuel. If it takes a few times than the fuel systems is not staying primed and the fuel is draining back into the gas tank.
