Hi all. Looking for some help. We have 2012 razr 570. Never had a problem with until this started. After not using for a few months it ran poor, it idled fine but would die and stall when giving it gas. i thought the gas may be old and fouling the plug. Drained the tank and new plug. ran great again. a few months later it started again. this time i changed the fuel but not the plug. ran great again. next day same problem. i pulled the fuel line and turned the engine over and gas was flowing. put it back and it started and ran fine.today same problem again. what am i missing. if anyone has an idea it will save me a trip in for service.The engine light comes on when you try to drive it not when it idles. no code just chk eng. i just hit 50 hours. thanks for any help
