After 10 minutes of operation mower stalls out and will restart but will die out again
Experienced gardeners share their insights in answering this question :
I was mowing along on my LA145, which had about 200 hours on it, and it slowed down then died. Before it died, it was acting like it was losing power. It felt like it was only firing on one cylinder. I waited a bit and it restarted after a lot of cranking. I made a couple mowing passes, and then the same thing happened.

Because I have mowed commercially for many years, I know my equipment inside and out. This mower was in top running condition and should not have been acting this way. There were no engine misses, no backfires and it was not normally hard to start. I knew the carburetor was clean, the coils were good, and the plugs were new. The fuel filter was recently changed. I got off, lifted the hood and gave a general inspection of the engine compartment. I noticed the fuel filter was nearly empty. I pulled the hose off the tank side of the filter and saw there was no flow.

The gas should gravity flow from the tank to the filter, if the tank has a good supply of fuel. Not that I recommend this practice, but I have no problem with doing it myself….I wiped the hose off and blew air back into the fuel tank. It helps to take the gas tank lid off first. After I got a good flow of air going back into the tank (it required several lungs full of air, you can hear the bubbles) the fuel began to gravity flow back through the hose at a decent clip. This fixed the problem. There is likely silt build up in the tank and it settles at the output port blocking the flow of fuel.

The problem repeated itself several times last summer. Back at the shop, I used compressed air to blow the line clear. The problem has not shown up in quite some time.

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 :

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.

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.

Other things that could cause this issue are bad fuel, weak/colapsed/kinked fuel line, faulty spark plug, faulty ignition/coil, oil over full, clogged air filter, plugged/dirty carburetor, worn engine parts internal rings/valves/etc.
As the fuel level drops, a vacuum begins to form in the fuel tank because air can get in to fill the space the consumed fuel occupied. After about 10 or 15 minutes, the vacuum will become strong enough that fuel will stop flowing to the carburetor and the lawnmower will die.
Why Does Your Lawn Mower Run for 30 Minutes Then Die? 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.
Condensation inside the gas tank is one culprit, but moisture can also enter the system through a loose or ill fitting gas cap. The best solution is to drain the mower`s gas tank and refill it with fresh gasoline. A clogged fuel filter can also cause a mower engine to die.
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.

If your lawnmower will start and run with the choke on but dies when the choke is turned off, it may have a problem with the carburetor. The carburetor brings air and fuel together and mixes them in the perfect ratio for combustion before they enter the engine.
The factors that keep draining your lawn mower battery include damaged, loose, or corroded cables, an electronic drain, or cables that are attached loosely. Sometimes, it is as simple as the battery needing some maintenance. Other plausible reasons are faulty alternators, voltage regulators, and battery chargers.
You can expect to get anywhere from six to ten years out of your riding mower, or longer with proper care and maintenance. Like most machines, riding lawn mower life varies depending on a number of factors including terrain, maintenance and upkeep, number of hours used, and more.
