Q: Snowmobile loses power, then dies and will not start back up.
1994 Yamaha Vmax 600 2 stroke. Starts up fine, runs good for about 5-10 minutes, then dies. Only starts if gas put directly into engine through pouring into spark plugs holes. Starts right up and will run for another good 5-10 minutes. Seems to lose power towards lower rpm but once it eventually gets up to the power band it is very fast and sounds great.
