## Discrepancy

LOSS OF TORQUE/IFSD  DURING CRUISE AT FL150, A LOSS OF POWER OCCURRED AND THE PILOT SHUT THE ENGINE DOWN.  AFTER DESCENDING TO FL100, THE PILOT RE-STARTED THE ENGINE NORMALLY BUT WHEN AUTOMATIC WAS SELECTED, THE TORQUE READ ZERO AGAIN. THE ENGINE WAS SHUTDOWN AND AN UNEVENTFUL SINGLE ENGINE LANDING FOLLOWED. TROUBLESHOOTING IS ON-GOING AND FOCUSING ON THE AUTOFEATHER UNIT.
