Narrative:

Returning from senney, nb, to denver stapleton at approximately 39 DME northeast of denver descending from 12000 to 8000 I noticed a small vibration. All engine instruments were ok. This lasted a few mins then the right hand mp began to drop and the engine was running very rough. I complied with the checklist, and was unable to keep the engine running so I secured it per the checklist. I notified ATC and company dispatch of the problem. I declared an emergency and ATC suggest that I go to front range airport which was closer. They gave me a vector to the airport and then I landed on 26 without any further problems.
