Narrative:
While at cruise the #1 engine flamed out. Requested descent from center and got clearance to FL240. So had been xfeeding fuel from tank #2 into engines #1 and #3. At the completion of xfeeding he closed the #1 and #3 xfeed valves, but then forgot to turn on the #1 boost tank pumps. Ran checklist as per company SOP and restarted at FL290. I feel that the fact that the boost pump lights were turned to dim caused the so not to notice that the pumps were off when he closed the xfeed valves. Callback conversation with reporter revealed the following information: reporter stated the fuel shutoff valve was not operated, only the xfeed shutoff valve was operated but the boost pumps in #1 tank were not on causing the #1 engine to flame out. The reporter advises the so realized immediately what he did and he started relight procedures.

Title: A B727-100 IN CRUISE AT FL350 EXPERIENCED #1 ENG FLAMEOUT CAUSED BY THE SO CLOSING #1 AND #3 XFEED VALVES AND FAILING TO TURN ON THE #1 TANK FUEL BOOST PUMPS.
Narrative: WHILE AT CRUISE THE #1 ENG FLAMED OUT. REQUESTED DSCNT FROM CTR AND GOT CLRNC TO FL240. SO HAD BEEN XFEEDING FUEL FROM TANK #2 INTO ENGS #1 AND #3. AT THE COMPLETION OF XFEEDING HE CLOSED THE #1 AND #3 XFEED VALVES, BUT THEN FORGOT TO TURN ON THE #1 BOOST TANK PUMPS. RAN CHKLIST AS PER COMPANY SOP AND RESTARTED AT FL290. I FEEL THAT THE FACT THAT THE BOOST PUMP LIGHTS WERE TURNED TO DIM CAUSED THE SO NOT TO NOTICE THAT THE PUMPS WERE OFF WHEN HE CLOSED THE XFEED VALVES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THE FUEL SHUTOFF VALVE WAS NOT OPERATED, ONLY THE XFEED SHUTOFF VALVE WAS OPERATED BUT THE BOOST PUMPS IN #1 TANK WERE NOT ON CAUSING THE #1 ENG TO FLAME OUT. THE RPTR ADVISES THE SO REALIZED IMMEDIATELY WHAT HE DID AND HE STARTED RELIGHT PROCS.
