    I would have the Trucks Computer Scan, just to be sure no Trouble Codes are Stored.....if no Codes you could look at the Following,

    .....Check the Fuel Pressure
    .....A Set of Plugs and Wires....for Plugs A/C Delco Iridium Tip Spark Plugs, for Wires either Factory/OEM(A/C Delco) or Aftermarket Wires
    .....Cleaning of the MAF Sensor.....and used only!!....CRC MAF Cleaner(Pictured Below)
    ....Cleaning of the Throttle Body and Injectors
    ....New Air and Fuel Filter's...If needed

    CRC MAF Cleaner

    being that its intermitant like this im leaning toward electrical its bad / then good if it were fuel i would think it would be bad all the time
