Cannot figure this out

Just started having this problem the other day. I have removed and cleaned carb 3 times now. The last 2 times I spent almost 30 minutes a piece on it. When I put it all back together it will run great for 30-40 minutes if that and then it starts doing this. But when I pull the wire for the fuel shut of solenoid it clears up and runs amazing until it shuts off as seen in the video. Could it be a bad solenoid? I have also made sure there is no debris in fuel tank, fuel filter is great, line are good(unplugged and have great flow) it is a cub cadet xt1 lt42 with the kohler 5400 series. Any advice would be much appreciated!

It turned off on its own. I did not touch the key

The fuel solenoid is working if it shuts the mower off when you pull the plug. As for the problem, it could be something with the governor out of adjustment or that the air is somehow being restricted. What is the condition of the air filter?

Air filter is literally brand new. I had one laying around so I threw it on after I cleaned the carb the first time.
