Narrative:

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 right 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.
