Qlink XP 200 Stalling on Open Throttle

Hi guys. I have a Qlink XP200 with just over 1,000 km. All I have done to it so far is change the oil and oil filter. The only thing I did not do that is listed in the manual as scheduled 1,000 km maintenance is clean the gasoline filter. After about an hour of riding it begins to sputter and will eventually stall upon opening the throttle even a little bit. For the first hour or so it runs perfect. Once it acts up I can let it cool down and it will run again for a little while. This sounds like it could be related to the gasoline filter but I am reaching out to see if anybody has insight into this issue. Thanks for the support.

does this only happen after you run with wide open throttle for a while? Then its most probably the fuel flow is too low and empty your carburetor. When you stop, restart and run in idle for a minute its gone. I had this in the past.
Second experience is a dying ignition coil. When they are done they make problems after getting warm/hot.

It does not only happen after wide open throttle. It has happened after trail riding sessions with varied throttle positions. The ignition coil diagnosis sounds probable. However, when it is happening it does fell like a fuel delivery issue.
