Losing power after 30 minutes at Full Throttle in one engine

My wife and I have taken our boat out several times after being on the water for about 30 minutes we lose power on one of the engines and a knocking sound I slow down and we just go about six nights for about 10 minutes and then it allows me to get back on plane again then after about 10 minutes it starts to do it again the RPM's stay consistent but it seems like the power to the prop is not spinning this is from a 454 MerCruiser twin-screw if anybody has any ideas it would be greatly appreciated
