Reason 2: Battery Draining Power
The battery on a Dewalt lawn mower is responsible for providing it the required power to run.
But, if dirt has badly attacked the battery and its compartment, the power flow can get interrupted. In some cases, a completely defective battery is the culprit.
Solution: Clean the Battery or Replace It
To get the power flow from the battery, wipe it and its compartment thoroughly with a dry cloth. If you catch the battery is defective, replace it without a second thought.
Reason 3: Less Air Than Needed
To run the lawn mower, just as fuel, air is also needed.
But, if the air filter is blocking air with its clogged state, the mower will fill the lack of air. And, due to it, the fuel mixture in air will be wrong and the engine may not run with it.
Solution: Inspect the Air Filter and Purify It
To free the air flow to the mower, inspect the air filter. Purify it considering the material it is made of. Otherwise, you may damage it while cleaning.
Reason 4: Old Fuel in Use
Old fuel in use is a common reason that helps the Dewalt lawn mower to stop running repeatedly.

An ignition coil is undoubtedly an important component of the Dewalt lawn mower.
But, as soon as it stops working, the process of igniting the sparks also stops. In other words, the engine doesn’t get the assistance from the ignition coil to function.
Solution: Check the Coil Connection
Many things can happen to the ignition coil and therefore, a better option is checking it evenly. In case there are any loose wires or connections, fix that without delay.
