I'm afraid you need to check ohm's law all electric motors will draw more current when the voltage drops. Also when the current is forced higher that means more amps are flowing through a wire that was designed for a lower current which means more HEAT. That heat leads to failure! If both voltage and current drop then your power drops lowering fuel pressure till the point the engine is not running efficiently or quits
