Carburetor Assembly
The most likely failure point is the internal metering circuit of the carburetor. Over time, ethanol-blended fuel evaporates and leaves behind a varnish that restricts the main jet or emulsion tube. This allows the engine to start on the rich fuel mixture provided by the primer bulb or choke, but causes it to stall once it attempts to draw fuel through the primary mechanical circuits.

Fuel Tank Cap
Small engines rely on atmospheric pressure to push fuel from the tank into the carburetor bowl. If the vent in the fuel cap is obstructed by debris or ice, a vacuum is created inside the tank as the engine consumes the initial fuel. This vacuum eventually overcomes gravity, stopping the flow of fuel and causing the engine to starve and stall shortly after startup.

Spark Plug (F7RTC)
A fouled or improperly gapped spark plug may have enough conductive surface area to fire during the high-volatility cold start phase but fails to maintain a consistent arc as the combustion chamber temperatures rise. Carbon deposits on the insulator can also create a shunt path for the electrical current, leading to intermittent spark and engine failure under light load.
