...I think my fuel config might have been the problem. The center tank had 3000 pounds and the wing tanks were full at takeoff. Once I reached cruise, i think the center tank ran out of fuel and the engines died. But the crossfeeds were all open so I guess I don't understand why the engines died. The engines wouldn't start up again until I turned the center pumps off.

Hi CXA546,

Doesn't matter if crossfeeds valves are open. Pay attention at F/E panel and be sure to close the valves and shut off pumps before each tank is almost empty (about 500 pounds) or the engines will die. The same thing happens with the B707.
