    rxDi surging loss of power issue

    2003 rxdi with fresh rebuild.
    After running at wot throttle for a minute or so the power drops off and it will surge. If I leave of throttle to idle for a few seconds sometime it will run good other times it will surge.
    Fuel pressure good.
    During one run the rear plug was fouled.
    My thought are possible plug lead or coil breaking down at wot.
    Any other suggestions please

    Why was it rebuilt in the first place? Were all 3 fuel filters replaced? You could have an over-charging rectifier. Put volt meter on battery, fire it up, then rev it up and see what the voltage does.
