I have a 2001 Honda TRX400 that fires right up and run for approx 5 mins then it just shuts down like someone hit the kill switch, it will fire right back up and run fine for another couple of mins and then dies. I have tested if the battery is taking charge and it is. What can I do to figure out exactly what is causing this? It does not have any pattern at all... I have wiggled wires around and checked wires while it's running and nothing seems to kill it, it kills itself at random but fires right back up.

Also it sometimes appears to miss a couple times but then goes back to normal idle before killing itself.

Could be a number of different things. But as always start with the easy stuff. New spark plug. Try putting fuel on reserve. Remove gas cap( Could be a tank vent issue.) There are a number of things common things that go bad when warmed up. Or cause random miss fires. When you change the plug try removing the spark plug boot off the wire and cutting about a 1/4 inch off and screwing back on.(It just unscrews off lefty loosy righty tighty). If none of that works i would start with coil. Then cdi. After i got a spark tester light and watched it act up with it on and saw the light flicker and go out when it shut off. That would confirm 100% its spark related. That should get you started in the right direction!

Nah only reason they say that is because you will be turning against the starter. It will usually be way easier to turn the other way. And very hard to turn the way you did it.
