    I am at my wit's end - My 760 runs like a champ WHEN it runs however, after 15 minutes it will die like it is out of fuel. Doesn't matter if it's in a turn, going straight, 20 mph or 70 mph...
    Every time it dies it reeks of fuel, but there isn't a fuel leak. It is as if the engine was flooded. I have replaced: the main fuel pump, the tank fuel pump, fuel filter (sock), the hose between tank fuel pump and sending unit, main fuel filter, fuel pressure regulator, vacuum hose between regulator and manifold, O2 sensor, and finally, the on-board CCU. After anytime ranging from 20 minutes to overnight, it will start right up and run like a champ! HELP! I am out of ideas! :confused:

    phanton faulty fuel system

    I had a similar problem that was finally tracked down to a faulty FUEL PUMP RELAY. It's a $25 to $50 plug in part that can be found on line.
    I hope this helps.
