has anyone had to deal with this problem or have any idea where to start looking for a solution? I have already run a diagnostic on the main relay, and it is perfectly good. any time I'm at constant speed, constant throttle, the fuel cuts out. If I apply a little more throttle pressure, the mixture goes rich, but as soon as I resume constant throttle and and speed, the fuel cuts out again. My guess is a short somewhere, but I'm not exactly certain how to diagnose this bugger.
