If you open the gas tank and give the ski 5 mins and prime the ski again the ski will turn back over and run for another 10 mins.l looked at the venting on the gas tank and l have one line that is laying on the bottom of the ski.Do not know if this line disconnected.All lines are connected to the gas tank.The ski seems like it is loosing air in the gas tank and the ski is working to hard to get the gas so it shouts off.Any ideas would be great

l dont know how they work on a jet ski but in my boat you hane a vent outlet coming out the side of the hull l would think it should be simular to that it sounds to me like its not getting air to thefuel tank l would check the vent line there should be no hose just lying on the bottom thats where you should start
