I purchased two Jet Ski‘s last month. The person I bought them from passed away last year and I am unsure how they were winterized. I took the Yamaha out about two weeks ago and had an absolute awesome blast on the water. After running it for a few days —out of the middle of nowhere the 2001 wave runner started shutting off. You can hear it’s starving for fuel and then totally shuts off. It is a bit difficult to restart but often I can get it restarted with no acceleration ability. If I wait it out and try it the next day it works perfectly for about fifteen minutes of operating and then repeats?? Where shall I start?
