On arrival into ZZZ descending from 15;000' to 11;000'; with power not at idle. I noticed that the #2 engine (Right) was unresponsive with notable power loss and associated yaw. We observed the fuel flow drop to Zero with a 300lb fuel imbalance between main tanks. We also observed the R engine oil pressure dropping as well. We ran the QRH for both the associated issues which instructed us to perform an in flight shut down and single engine landing. We accomplished the checklists and QRH safely. No further incidents observed. Unknown cause. Engine had an uncommanded rollback of power with subsequent loss of engine. QRH procedures followed. I don't believe anything could have been done differently. All normal operations were followed as well as QRH procedures followed.
On arrival into ZZZ descending from 15;000 to 11;000; with power not at idle. Our right engine became unresponsive; with notable power loss; and associated yaw.  Watched fuel go to 0; with a 300 lbs. imbalance between main ranks. Ran low fuel press QRH and low oil press QRH. Instructed us to do an inflight shut down; and single engine landing. Which we accomplished safely. Unknown at this time. Right engine had an uncommanded roll back. Single engine shut down and landing. Nothing we already do single engine shut down and landing.
Flight crew reported an uncommanded power rollback in the right engine; which resulted in an inflight shutdown and a subsequent landing.
