Check pump sometimes they go bad.

I would run a mechanical pump. You can hook a gas can up directly to the pump and see if the problem goes away. That method allows you to divide and conquer the fuel system. If it runs correctly, you know to go back towards the tank. If it’s still running poorly, you have a carburetor problem or a non-fuel issue altogether.
