2014 Kymco Super 8 150 Running Issues

[FCSSensai]

She starts, idles fine, runs fine. Will run 50 mph for a hour to 4 hours then suddenly she will start dying out, and cut off completely. She then will crank but not start, and after a day or so will start up just fine like nothing happened then the cycle continues. Any advice?

Check that the gas cap is venting

When it dies, do you hear air sucking in when you crack open the gas cap?

Also have read reports of electrical parts temporarily shutting down when they get too hot for too long..

It does vent, no suction. I do notice when trying to start no fuel is circulating through that little tube at the top of the tank. I don’t think it’s a heat problem, I’ve ran it for 2 hours in 90 degree heat just fine, and then turned and had issues after 39 mins on a cool day. Really weird. I will however inspect everything to see if anything is getting abnormally hot that I can tell. This would be stuff like the black box by the battery and such right?

You'll need advice from others who are familiar with carbs - (I haven't dealt with a carb since the 60's) since you are not seeing fuel flow.
It does not sound like it is a heat issue with electrical parts.
