At the end of the session I was going about 20mph and went to get it up to 30mph and I had nothing. zero power. The boat would go in gear but I had no power. Went home and discovered thru WW that the knob on the PP had come loose. Got it tightened back up and we went out this last weekend. We started to go and I could only get the boat up the maybe 18mph max, you could tell there was something wrong so I check the PP knob(seemed good) and we fiddled with it for a while. There was a what sounded like the motor was missing and had a little popping when being labored. Since we couldn't get to wakeboard speeds we decided to fill the tanks and surf. We did that and start going It was starting to labor more and sound like it was starving for gas and miss firing/popping. So we shut her down, emptied the tanks, I let my kids swim for 15 min or so and we start back to the dock. We started going back and all of a sudden I had great throttle response, I got it going to 40mph and was very confused. Brought it back to a stop and started going again and everything was working fine. We boarded and surf without issue for the next 3-4hrs. So my question is as I pack for a week of camping/boating, is the boat fixed, what could of been the problem? Is there still an underlying problem? My buddies and I were thinkin I run some fuel or injector cleaner thru it? Any help would be appreciated.

Sounds like you are having fuel delivery issues to me as well. The popping you are describing are "lean pops". Main culprits - fuel pump, water in gas, fuel/water separator/filter clogged?
To answer your question, the problem likely hasn't entirely worked its way out and could still be an issue. If you aren't going to do anything about it, at the very least get some Blue Stabil and run non-ethanol premium through it.
