Narrative:

Had an uncommanded shutdown of the right engine while cruising at FL380. Myself (captain X) and captain Y had just arrived on the flight deck from our crew rest break five minutes before. The engine spontaneously shut down without warning at which point we began the off track divert procedure and commenced with the checklist. I referenced the altitude page; preferring to divert to ZZZ; but determined it was too far to fly on one engine. The engine would not relight despite showing no obvious signs of damage (N1-23%;N2-17%; egt; oil pressure-11 psi were all in expected range for wind milling engine cross start). A flight was nearby and heard the call and initiated contact with dispatch to advise them of our situation. I was flying and the captain handled the communication and checklist items. The flight attendants were notified and our fb and fc promptly returned to the flight deck. Approximately 15 minutes after engine loss; a restart was attempted for the following reasons; no abnormal engine indications were observed and we were almost two hours from our suitable alternate. Due to the overwhelming amount of data coming into the aircraft; the datalink locked up for about 15 minutes. We received a comm busy message and could not receive any messages. The printer was intermittent.delegation of duties: captain X was flying; captain Y preformed all of the checklists and VHF communications; fb communicated with dispatch; calls to ATC; and communication with the flight attendants; fc was tasked with overview; deciphering NOTAMS; approach/landing normal and non-normal procedures. A successful 20 degree flap landing was made at ZZZ. Landing weight was 374.2. We stopped the aircraft on the runway in order for arff to accomplish a damage inspection. No abnormal conditions were apparent and a subsequent taxi was made to the hardstand. The airport manager was contacted well prior (the flight had nearly 2 hrs of single engine cruise). Arrangements were made to have stairs and equipment available in this remote airport. We complied with the department of transportation 4 hour requirement to offer the passengers to deplane the aircraft. [The flight crew] did an outstanding job providing valuable planning insight; operational procedures; cabin and passenger oversight; and arrangements and solutions to a variety of issues.
