Narrative:

Normal landing at ZZZ. After required cool down period; shut down right engine during taxi to gate. As taxi-in continued; left engine experienced an uncommanded shutdown. Notified maintenance; restarted right engine; and taxied to gate. Lessons learned: we had already crossed all of the active runways; but this is a good reminder as to why it is important to keep both engines running until you have safely crossed all active runways.
