I included the engine speed sensor in the list of possible suspects, because a loss of TDC signal of just 1 second shuts off the fuel pump relay instantaneously. It's like someone reached over and turned off the ignition key. That's a fire prevention safety feature in case the vehicle was involved in a collision as the reason why the engine speed suddenly went to zero. Of course, with a malfunctioning sensor, the car doesn't know that you weren't involved in a collision, so the fuel power supply is immediately cutoff via the pump relay.
