Narrative:

We were cleared for takeoff on runway xxl; I was the pilot flying. During the initial climb the aircraft began a yaw to the right. There wasn't any caution or warning messages to cancel and identify. The captain indicated to me the N1 was at idle and asked for the controls. We completed emergency procedures and [advised] ATC and asked for vectors to return to the field. The right engine restarted so we asked ATC for vectors to a hold so we could burn fuel. We inform dispatch of the [event] and that we were overweight; they advised us to return to ZZZ.
