Hay Guys I'm having a problem with my promax it will run just fine I get on plain and trim out then the power drops in half. If I keep my foot in it will jump back to full power. This may take a few seconds or as long as a few min. Then it may not do it again for the rest of the day. I have replaced all fuel lines,injectors and filters as well as temp sen. Voltages all look good and stator ohms out ok. Any ideas".... Sorry ser number on motor 0g361816
