yes the Marrelli Digiplex could certianly be the culprit. I also have seen the rev limiters go haywire and shut off the fuel pumps at wrong RPMsraymond said:Sometimes the rev limiter goes mad and cuts off the engine, unmount the ignition box and clean all connections between the big box and the two bolt on units.
Mine ran a lot better afterwards, but for real power install an MSD-Unit...
Of course the things that John mentioned have to be checked too!
