Need some advice

Carefully remove the fuel filter. Get some paper towels and place them on the ground and empty the fuel filter with the outlet facing down. Sounds like a fuel problem and I bet you see some debris in the fuel. If so, you will need to flush the entire fuel system including removing and rinsing the tank and intstalling new rubber hoses (only about 12" worth) and a new fuel filter. You may need a kit in the carburetor as well. But the fuel filter test will confirm or rule all that out.
