2005 Honda Rancher 400AT dies when warm

2005 Have a Honda rancher 400AT that dies when it gets warm. It will start back up when it cools down, not sure what it could be? Any help would be appreciated. Cleaned carb, changed voltage regulator and stator. You can rev it up and it runs fine when it has net yet warmed up. Will not restart until cooled down some.

Had this issue recently with an Arctic Cat build, turns out that the spark plug gap was ridiculously small and the plug boot was very worn inside where it locates onto the plug, new spark plug and boot fixed the issue completely.

I’ve never experienced an issue like this so that’s all I have to offer. Might be worth a shot before you throw money at it.
