Default After 10 - 15 minutes of riding loses all the power

After driving my ATV (GY6 150cc, CVT transimission) for about 15 minutes it always loses all the power. First 30% of the throttle is OK, but there isn't anything beyond. Then let it sit for a 3 - 5 hours and it's back to normal. Again at full power.

Drive it for 15 minutes and it's without power. Let it sit for few hours and it's cured.

My only thoughts is either temperature or something is getting wet - it's raining season over here. HOT or WET is something what occurs within 15 minutes and goes away in a few hours on its own.

I only checked carburetor air intake filter, but it's not a problem. I don't know what to check next...

Here's the video, but audio/video is a split of second out of sync:
