If an engine won't crank, it is a battery, starter, solenoid or wiring problem. Cranking means "engine turning over". If you mean that it cranks/turns over but won't start, then that is a different problem.
An engine needs air, compression, good fuel and good spark to run. It could be something simple like bad fuel or weak spark. It could be that the spark timing is off. It could also be low compression. (A worn cylinder or valves that are adjusted too tight or open/off their seats) It could be getting too much fuel or not enough fuel.

Why wont my Four wheeler battery stay charged?
i had the same exact problem with my 2001 polaris sportsman 400. It is either your voltage regulator or your stator. With your ATV running disconnect the positive terminal on your battery. IF the ATV quits instantly then its probably your stator.
