Narrative:

ATC requested a climb from FL370 to FL390 due to converging traffic at FL370. I checked the performance charts, and we were right at the maximum weight at the conditions to maintain FL390, so I accepted the climb. Upon climbing through FL380, ATC issued a time restr to be level at FL390. I was just starting to level at FL390 with about 10 seconds left on the time restr when the right engine flamed out. I advised ATC of the situation, and that we were unable to maintain FL390. ATC requested a 30 degree left turn if able, and I complied. I am uncertain if ATC requested a turn from the converging traffic. We never established visual contact with the traffic, but they reported contact with us via TCASII and informed ATC that we passed behind them. I do not believe that traffic separation was ever compromised, but I am not certain. I believe that given the conditions, if ATC had informed me of the time restr when they issued the climb instructions, I would have told them I was unable. In the future, I will not hesitate to ask about any possible time restrs for a climb. We had to descend to FL270 to enter the relight envelope. The engine was started, and the flight continued normally. I believe the flameout was caused by turbulence combined with a high angle of attack.

Title: LTT CARGO JET ENG FLAMEOUT DURING HIGH ALT CLB. RESTARTED AT A LOWER ALT.

Narrative: ATC REQUESTED A CLB FROM FL370 TO FL390 DUE TO CONVERGING TFC AT FL370. I CHKED THE PERFORMANCE CHARTS, AND WE WERE RIGHT AT THE MAX WT AT THE CONDITIONS TO MAINTAIN FL390, SO I ACCEPTED THE CLB. UPON CLBING THROUGH FL380, ATC ISSUED A TIME RESTR TO BE LEVEL AT FL390. I WAS JUST STARTING TO LEVEL AT FL390 WITH ABOUT 10 SECONDS LEFT ON THE TIME RESTR WHEN THE R ENG FLAMED OUT. I ADVISED ATC OF THE SIT, AND THAT WE WERE UNABLE TO MAINTAIN FL390. ATC REQUESTED A 30 DEG L TURN IF ABLE, AND I COMPLIED. I AM UNCERTAIN IF ATC REQUESTED A TURN FROM THE CONVERGING TFC. WE NEVER ESTABLISHED VISUAL CONTACT WITH THE TFC, BUT THEY RPTED CONTACT WITH US VIA TCASII AND INFORMED ATC THAT WE PASSED BEHIND THEM. I DO NOT BELIEVE THAT TFC SEPARATION WAS EVER COMPROMISED, BUT I AM NOT CERTAIN. I BELIEVE THAT GIVEN THE CONDITIONS, IF ATC HAD INFORMED ME OF THE TIME RESTR WHEN THEY ISSUED THE CLB INSTRUCTIONS, I WOULD HAVE TOLD THEM I WAS UNABLE. IN THE FUTURE, I WILL NOT HESITATE TO ASK ABOUT ANY POSSIBLE TIME RESTRS FOR A CLB. WE HAD TO DSND TO FL270 TO ENTER THE RELIGHT ENVELOPE. THE ENG WAS STARTED, AND THE FLT CONTINUED NORMALLY. I BELIEVE THE FLAMEOUT WAS CAUSED BY TURB COMBINED WITH A HIGH ANGLE OF ATTACK.
