    Default 1996 k1500 4x4 5.7 automatic misfire mystery

    I have never posted for help on a forum before........but I am at the end of my rope.

    Multiple random misfires on random cylinders under load.

    I have installed new:
    Cam Position Sensor
    Crank Position Sensor
    Distributor cap and rotor
    Plug wires
    Spark Plugs
    Catalytic converters
    All O2 sensors
    Fuel pump and sending unit
    Fuel filter
    MAF sensor
    Air temp sensor

    I haven't had the truck long.....not even long enough to get inspection and tags. I drove it for 70 miles Friday afternoon without incident.....later that evening the misfiring started.

    No codes. Seems like it is losing current....the reason I say this is because without disconnecting the battery the clock on the radio resets randomly.

    PS: no miss at idle no matter what rpm.

    Any input would be greatly appreciated.
