Narrative:

At XA30, I was performing a formation demonstration flight in ZZZ, us. I was flight lead of a flight of seven. I had an alarm on fuel pressure, and a few seconds later the engine coughed. I immediately pitched up and out of the flight and advised the airbus I was landing. The engine stopped making power. I xferred the flight responsibilities to my #4 as briefed. The air boss cleared me to land. I landed on the runway without incident. Upon stopping, I engaged the electrical fuel pump and the engine restarted. I taxied to parking. Further investigation revealed a failed mechanical fuel pump. As a corrective action, I will engage my electric fuel pump when flying low level formation.
