Narrative:

Level at FL390 with occasional light turbulence tank to engine fuel feed #1 ignition on. Aircraft weight 555000 pounds. We experienced a sudden jolt and #2 engine began to unspool. Within 30 seconds #3 engine began to unspool. First officer requested lower altitude, captain was flying. The first officer and I began the engine shutdown checklist. After engine shutdown all engine parameters appeared normal so we began the restart procedure. Both engines restarted with no problems before we reached FL300. We then requested FL350 and continued to hkg with no further incident.
