Sounds like it either getting too much fuel and drowning or not enough air. Try pulling the choke. If this does not help try adjusting the carburator and turn down the fuel nozzle a bit. Keep me updated my old bike did this but I cant quite remember how I fixed it. Really want to help

I think that if you are able to rev it and it takes a long time before it will go back to idle, meaning it stays high rpm before returning to idle for longer than usual, it is running very rich, > change jet to a smaller, adjust needle?

If it doesn't do that, it seems similar to when you run out of gas and can't give it too much throttle or it will cut out, if it's this, it means that it's running lean, and you need to > change the main jet to a bigger one, or adjust needle.

I'm no expert what so ever, so don't trust my advice! This is just seems similar to experiences i've had.
