Hello all. Need some advice. Just recently took my GTX out of the garage but haven't rode it in about 20 months. Put a new battery in, changed the oil and oil filter and changed the spark plugs. Started fine dry and took it to the lake and everything worked fine for about 45 minutes. Had good rpm and speed topped out around 54 mph with two people. I was in the middle of a turn and then I started loosing rpm, the ski started acting rough and eventually quit and would not start. RPM would get between 250 and 480 but would not start. After several attempts I let it set for about 45 minutes. Started up but only ran for about 1 minute and then I would loose the rpm and it would die. Could this be a fuel starvation issue or could the fuel filter be stopped up or maybe something worse. Thanks for any reply.
