Have replaced primer and fuel lines from tank to mechanical pump, voltage regulator was burnt at the plug had to also replace stator due to plug being burnt. Still sputters and shuts down half throttle and above. Mercury tech said check screen on high pressure pump was pretty black replaced that and the pump as well as the mechanical pump. Still same thing half and above. Running out of ideas oh ya also nuetral safety switch and lanyard are bypassed for testing purposes and key switch tests good. Same problem would like any input if anyone has any other ideas any help would be greatly appreciated thank you.
