Sounds like you have a fuel pressure issue. These trucks are bad about bleeding all the fuel pressure off when the engine is shut of but will run fine when started. the only good way to check this is to install a fuel pressure gauge on the shrader valve on the fuel rail. Once you get it isntalled start the engine and let it run for a minute or so,shut the engine off and it should hold pressure,if it bleeds off quickly it means the check valve on the pump is leaking and it will need a fuel pump.
