I've had this issue with these trucks in the past with fuel injectors that bleed down when they were warm intermittently. The easiest way that I've found to diagnose them is to remove the two eight millimeter bolts that holds down the fuel rail, spray the base of the injectors with penetrant, wiggle the injectors side to side to break the seal, lift up one side of the rail slowly until all of the injectors are off of the intake then suspend the rail with a bungee cord and look for fuel dripping. The engine should be warmed up before trying this and use a flashlight because sometimes the mist is really hard to see. It's a quick and easy test, and if you have any of the dripping you can replace them while they are out.
