Most problems that will cause a John Deere lawn mower to stall after 20 minutes occur due to the distribution and rate of flow in the fuel and air systems. If these systems are dirty or restricted, the mower will stall out and be difficult to restart.
If your lawnmower starts up but then dies in the middle of mowing your lawn, you could have a bad spark plug. The spark plug works with the ignition coil to create a timed spark in the cylinder, causing combustion. The spark plug is really a very simple device.
The spark plugs are worn or damaged
If you find that your lawnmower keeps dying, or keeps stalling while cutting grass, then inspect the spark plugs. Look for signs of damage or wear. Something as simple as a cracked porcelain insulator can mean an electrode has been damaged or burned away.
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.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit. Your engine needs air to run properly as well.
There is a simple answer to this and again it is to do with the clutch pedal. To avoid stalling when slowing down, push the clutch pedal down completely, just before your vehicle becomes stationary. Failure to do so will result in the car stalling.
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 cause of a mower that runs for thirty minutes and then dies is a faulty armature. A faulty gas cap is the second most likely cause.
A dirty air filter inhibits the flow of air into the carburetor. Clean or replace the air filter to stop the mower from sputtering to a halt. Too much air can also cause problems for the engine. A bad cap on the gas tank is the first place to look.
Use Carburetor Cleaner
Fortunately, you can generally do this without even taking the carburetor out of the engine. Start by purchasing some commercial lawnmower carburetor cleanerOpens a new window, which comes in a simple spray can and will make it easy to clean the inside and outside of the carb.
Tractor may be starving for fuel
The fuel tank can develop a vacuum. This could cause fuel to stop running to the engine – causing it to stall. If this is the case, give it an hour or two, and the tank pressure will reset and equalize. Then the tractor will run again.

I have John Deere GX345. It does not start consistently. When it doesn’t start the plugs have no spark. The problem is intermittent.All electrical connections look clean and no corrosion. Re- seated all connections. Fuel flow is good because I can smell raw fuel while cranking the motor. I replaced the fuel lines last year. Thank you for your help. Daryl Witowski
Look for a small silver box with 1 wire on it mounted to the motor. It is a temp sensor and will keep it from firing…Just had to replace mine…
