Narrative:

At the beginning of our descent into ZZZ; shortly after the engines had reduced power; the left engine rolled back completely and shut itself down. We notified center; declared an emergency; and performed the engine fail checklist. Since we were near ZZZ at the time we chose that as our diversion airport. We attempted one restart per the checklist and the engine remained unresponsive. Remaining checklists were performed and an uneventful landing was made at ZZZ in clear and calm WX. Callback conversation with reporter revealed the following information: maintenance discovered that a variable stator actuator had failed and caused the engine to be shut down by the fadec to prevent compressor stalls.
