Potential Difference (the voltage) acts as a pump for the electrons - when the pump runs out of energy, the electrons stop being pushed round the circuit.

A current only flows when the electrons are in motion.

because the potential dieffernce when decreases between the battery and the load, the electrons cannot flow and the electron flow is stopped
