Narrative:

While enroute; I heard a snap and some caution lights came on. The caution lights were the number 1 ecu and the number 1 fuel tank low caution light. I notice the torque on the number 1 engine had fallen to 3.8 percent. The aircraft did not yaw when this event occurred. We ran the ecu checklist; but there was no improvement. I slowly retarded the number 1 power lever to confirm that the engine was no longer producing power. It was not so we elected to shut down the number 1 engine I suspected we had a tq motor failure. After calling mtc; I found two more circuit breakers popped the number 1 tq cond; and the number 1 auto temp controller.we ran some checklists and talked to the first officer to decide what was going on. Once we concluded the number 1 engine was not producing any power; we shut down that engine. Ran all the checklist. Declared an emergency. Notified company and made announcements to the people.
