Narrative:

Simultaneous flameout of engines #1 and #4. Accomplished 'rapid engine restart' checklist. Engine #4 started on first attempt. Engine #1 started on second attempt. Fuel panel confign was main tanks #2 and #3 feeding all 4 engines. Center ovrd/jett pumps off/scavenge pump on. Had been in the confign about 10 mins. Fuel heat was off. All indications were normal. Declared emergency, turned off track, lost 1200 ft before able to restart engines and return to altitude and course. Callback conversation with reporter revealed the following information: although reporter was not in the flight deck when all of this happened, he was able to see the procedural steps to restart the engines. He reported that fuel feed from tanks was proper and nothing was done to induce the engines to flameout. Maintenance checked all fuel system electrical wiring and fuel supply line valves. Everything was checked on the ground to be working properly. Captain and first officer spent some time in the simulator reviewing the flameout scenario. Reporter was not in the flight deck so he was not invited to participate in review. There was a check airman on board in the flight deck and he saw no procedural errors by the flight crew. Reporter could offer no explanation of why the engines flamed out.
