Sounds like fuel starvation. so......
2 things. you are either getting fuel or your not (What???)
not getting fuel..... pull the fuel line off the carb and let the fuel run into something. Should flow evenly till the tank goes empty. That's good.
if not check the inside of the tank to make sure its clean and the outlet is clear and clean. While you are at it replace the fuel line. They rot from the inside out. They can block internally and restrict flow or flat out stop it.
Getting fuel. .... several things here.
Fuel not being delivered by carb = float sticking.
Vapor lock.... several things
Engine getting too hot. Clean the head and engine of all gunk and debris. Fuel line running close to the engine causing fuel to boil in fuel line. Head gasket failure.
Take the hood off and mow see if it helps.
FUEL PM. stay away from fuel with ethanol in it.
