Narrative:

After landing; we taxied to our gate where we verified/verbalized the safety zone was clear; followed the marshaller's guidance; and parked with the left engine running. While waiting for ground power to be plugged in the plane started to vibrate and I immediately shutdown the engine; after which the plane went dark. After explaining the situation to our passengers and getting electrical power restored; I went down to the ramp and observed that the left engine had ingested a large quantity of the yellow aircraft [air conditioning] hose.
