Hi Dewayne, I think you may have a problem with the coil. It sounds like it’s heating up while running and then it’s open too much. It may also be muck in the fuel tank. Check them both.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

A clogged carburetor is most commonly caused by leaving fuel in the lawn mower for a long period of time. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the engine to stall.
A Dirty Carburetor Can Cause a Lawnmower To Start Then Die

By far, the most common issue that causes a stalled motor is a dirty carburetor. The carburetor on your engine is the thing that draws in air and mixes it with the fuel. Contrary to what the movies might make you think, gasoline itself is not very flammable.

Clogged or Dirty Air Filters

Dirty air filters are one of the most common reasons lawn mowers sputter. Dirt can be present in the apertures that lead from the carburetor and the fuel filter and interrupt the flow of fuel supply to the combustion chamber. You want to be sure to clean or replace dirty air filters.

Bad gas, clogged fuel filter or gummed up carb. I`d suggest changing the gas, inspect or replace fuel filter and using either additive in the fuel or gumout into the carb, try to get that cleaned up some. While looking at the fuel system, also check the fuel lines for any cracks or rot that may be letting air get in.
A full gas tank and oil reservoir are the essential first steps when checking why the lawn mower won`t stay running, but the problem could also be a dirty filter, clogged carburetor, improper fuel mixture, or a dirty spark plug.
Your lawn mower runs for 30 minutes then dies if you are having issues such as a bad spark plug, air problems, a malfunctioning carburetor, or a faulty gas cap. You may even encounter the issue that your lawn mower runs for 5 minutes then dies.
Loose, Dirty or Disconnected Spark Plug in Your Lawn Mower: Check it out, clean off debris, re-connect and tighten. Dirty Air Filter: Clean or replace. Fuel Not Reaching the Engine: Tap the side of the carburetor to help the flow of gas. If this doesn`t work, you might need a new fuel filter.
The most common reason for a surging lawn mower engine is a blockage in the fuel supply, but there are other possibilities: Bad gas. Bad spark plug. Dirty/faulty carburetor.
The fault could be a dirty spark plug, air filter or carburetor, or it could be related to the quality of the gasoline used. Slow starting can also be the result of a failure to clean the blades. In most cases, you should be able to restore performance yourself.

Mower Gas Cap

If the tank is sealed, the fuel becomes air locked, and the mower stalls. This typically happens after a short period between ten and thirty minutes and also depends on factors like weather and gas tank fuel level.

Cranks up and runs fine ,then starts cutting out then runs fine and starts cutting out again
ANSWER : I am no pro but my suggestion to you is if you have changed your spark plug recently check the gap on it and make sure it is right and make sure is the right spark plug for it. Also check the oil if it is low the motor as it gets hot will start to sputter or if it has to much oil it will have an air lock and blow you Lhead gasket after a while. Another thing to check is the air filter to make sure it is clean and check the timing with this if you don’t trust your self ask an repair expert for your brand of mower.
