Could a failing Fuel Shut-off Solenoid cause the EXMARK RADIUS E-SERIES to have symptom: Starts Then Dies?

This electromechanical plunger sits at the base of the carburetor bowl to prevent backfiring. If the solenoid coil fails or the plunger becomes contaminated with fuel varnish, it will restrict fuel flow to the main jet immediately after the engine fires, causing it to stall. This is the most common failure point for Kawasaki engines that start but cannot sustain a 'run' state.

Could a failing Vacuum Pulse Fuel Pump cause the EXMARK RADIUS E-SERIES to have symptom: Starts Then Dies?

The Radius utilizes a pump driven by crankcase pressure pulses to move fuel from the low-mounted tank to the carburetor. If the internal diaphragm is torn or the vacuum pulse line is compromised, the engine will start using the fuel remaining in the carburetor float bowl but will die once that limited volume is consumed, as the pump cannot replenish the supply.

Could a failing Inline Fuel Filter cause the EXMARK RADIUS E-SERIES to have symptom: Starts Then Dies?

A partially clogged filter creates a pressure drop that allows enough fuel to seep through for a cold start, but cannot maintain the flow rate required once the engine's RPM increases. This causes a lean-out condition where the engine starves for fuel within seconds of ignition.
