An apparatus and method is provided for automatic shut-off of a combustion engine driving a fluid pump of a fluid displacement unit in order to protect the fluid displacement unit from damage due to excessively high running speeds. The apparatus includes a latching circuit that trips when an attention electrical signal exceeds a shut-off threshold potential. A biased electrical switching component inhibits fuel ignition for a period of time allowing the engine to spin down to rest. The latching circuit and switching component thus prevent the engine from being flooded to which prior-art devices are prone when their mechanical latches are not reset. Furthermore, this apparatus and method saves the engine from overspeeding damage to which prior-art devices are prone when a user blocks the mechanical latching action.
