What is a fuel pump cutoff switch?
The fuel pump cut-off switch works like a circuit breaker and cuts the power from the electric fuel pump in the event of a collision. This keeps fuel from leaving the fuel tank to minimize the chance of fire. If your fuel pump cut-off switch is failing, it may cause your engine to shut off randomly. via

What causes a fuel pump relay to go bad?
The most common cause of a fuel pump relay going bad is electrical power surges that increase the voltage. The fuel pump relay is designed to have a winding that causes contacts to pass current or voltage. What is this? In some cases, the current or voltage might be so high that the contacts get burned. via
Can a bad ignition switch cause no power to fuel pump?
If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system. This will cause the vehicle to immediately stall due to fuel and spark being cut off. via
