I have a Polaris Ranger 400 (2011 model) and it has just started to give me a problem. After riding it for about 15 minutes, it will die and won't start until it cools off (at least 30 minutes to cool completely down). It will then start and do the same thing. I've taken it to a Polaris dealer and they could not fix it but didn't mind charging me $400 to try. I know it's probably something simple like one of the electronic components flaking out but I don't know which one (coil, CDI-system, solenoid, spark plug cap, etc.). I hate to just start buying each one until I find the problem because I'm looking at about $600 for these four components that I see on "Polaris Partshouse" .com

Any advise ?
