Hard lesson learned. I Purchased a 1992 Starcraft Fish and Ski with Force 70 hp in August 2015. Ran perfect up to the last run of the season when I started to feel a slight power loss but blew it off until the next season in May of 2016. First run on the lake 5 minutes into WOT the engine shut down hard. I gave it a moment and it fired right up but i could not get it to come up on plain without it wanting to stall. This continued for weeks of trial and error. I did all the recommended stuff like clean and rebuild carb, rebuild fuel pump, change fuel filter, check the fuel tank vent, bypassed fuel system with an external fuel tank and hose, and lastly static timed the ignition. The simple truth about what my problem actually was is when I went to check the ignition timing, when I went to loosen the jamb nut on the timing advance/retard block, I could turn it by hand and it wasn't even close to being tightened up. Turns out that the timing adjuster screw was probably just vibrating back and forth in and out of the correct timing degree range of 28 to 32 degrees. So I set the timing, applied some Loctite the the jamb nut and secured it snugly, an hit the lake. Never had another issue after that. The entire time during that few weeks of trying to find the issue I kept reading "check the timing...check the timing" but I kept telling myself "the timing can't be that bad because it starts and sometimes I could gradually ease it up on plane for a little while. If I would have just LOOKED at the jamb nut I would have been able to see that it was about a eighth of an inch from being tightened against the locking point. My wife was standing right next to me when I discovered this and just laughed and called me a dumb ass!
