Hi i'm new here and my truck has an issue as to when i start it usually after its been sitting for at least a couple of hours that it will jump to life and then die. as if its not get fuel and ill crank it again and it will seem as if its getting less fuel. then if i turn off the ignition and pull the key out and wait for maybe 10 seconds and try again it will start normally. Any ideas to what this may be?

I would say do a full tune-up (depending on the milage of the truck) it wouldn't hurt, then go from there.

Pull the vacuum line off the fuel pressure regulator and see if any gas comes out of either the regulator or line. Do this while the truck is running. BTW, the FPR is on the driver's side of the engine, in the middle of the fuel rail. If you spot any gas, then the regulator is bad and needs replaced.
