    2006 stx 15f has no power under load

    Out of the water it runs great , revs all the way to redline but once i put it in it wont rev past 5k. It cuts in and out with a too speed of about 45. So far i checked the fuel pressure and compression and both are perfect as well as changed the plugs and oil. Anyone have any ideas?
