## Discrepancy

DURING CRUISE, EN ROUTE FROM CLT TO ROC, CREW REPORTED THE NR 2 ENGINE FLAMED OUT (AND THE CROSSFEED LIGHT EXTINGUISHED) WHILE CROSSFEEDING FUEL AT FL370.  CREW DECLARED AN EMERGENCY TO CLEAR TRAFFIC AND DESCEND TO LOWER ALTITUDE AND WAS ABLE TO RESTART NR 2 ENGINE AT FL220.  EMERGENCY WAS TERMINATED ONCE RESTART PROCEDURES WERE COMPLETED AND EVERYTHING WAS FUNCTIONING BACK TO NORMAL.  DISPATCH ADVISED FLIGHT TO DIVERT TO PIT WHERE THE FLIGHT LANDED WITHOUT FURTHER INCIDENT.  AFTER LANDING, CREW FOUND THE CROSSFEED BREAKER HAD POPPED.  MAINTENANCE PERFORMED TEST OF FUEL CROSSFEED SYSTEM PER MM 28-22-00-715.  SYSTEM OPS CHECKS NORMAL.  RAN BOTH ENGINES AS PRECAUTIONARY.  ALL FUEL SYSTEMS AND ENGINE RUNS NORMAL.
