I have a 2009 RTV 500 with 460 hours on it. In the last month it will start and run good. If you shut it off and try to restart, it will fire once on each cylinder then stop like it ran out of gas. If you try to restart, it will just crank over and not start and you do not hear fuel pump come on. I put it in garage over night tried next morning turn key to run hear fuel pump come on and it will start and run fine. Use unit for a while start and stopping ok then back to no start. It may be fuel pump but before I get into it just wondering if any one has had this problem and what the fix is.
