What was found
ABOUT 3 HOURS INTO THE FLIGHT WE WERE INSTRUCTED TO DESCEND FROM FL450 DOWN TO FL380. PASSING THROUGH APPROXIMATELY FL400 WE GOT A GEN OFF L ANNUNCIATOR, WE THEN GOT A OIL PRESS LOW L ANNUNCIATOR, FOLLOWED BY A LOSS OF POWER AND A ROLL BACK ON BOTH N1 AND N2. SUBSEQUENTLY WE GOT HYD FLOW LOW L, FUEL LOW PRESS L ANNUNCIATORS. I FOLLOWED THE EMERGENCY CHECKLIST AND COMPLETED THE ENGINE FAILURE/ PRECAUTIONARY SHUTDOWN CHECKLIST FOLLOWED A FEW MINUTES LATER BY THE EMERGENCY RESTART CHECKLIST AND WAS ABLE TO GET THE ENGINE TO RESTART EVEN THOUGH IT SEEMED TO STRUGGLE. THE ENGINE FUNCTIONED NORMALLY AFTER THAT.
