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.
The most common reason your car starts then dies immediately is because of a lack of fuel in the engine. This often happens because there is a small amount of fuel in the fuel rail, which helps to start the engine. However, there is no fuel pressure to keep the engine running.
Knowing you can expect your residential lawn mower to last you around 450-500 hours is helpful in the decision-making process. The closer you are to the end of the expected lifespan, the more you should consider replacing it if a large issue occurs.

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.
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.
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.
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.
Air must replace gas as it leaves the tank. A vented cap allows your mower gas tank to breathe, and that`s important. What is this? A blocked gas cap is a common cause of engine stall, (more on this below).

Answer: After the engine is shut off, its temperature rises. This excessive heat and pressure in the combustion chamber is what causes detonation, which ignites the residual fuel-air mixture in there.

This is most likely a safety switch issue. Usually the seat safety switch will cause this problem. The mower dies because it thinks nobody is sitting in the seat, and shuts off for safety reasons.
