Outside the OM for the ILS; ECAM advised ENG 2 FUEL CTL FAULT.  Almost immediately after; ECAM advised ENG 2 FAIL followed by complete loss of thrust.  ECAM then advised FAC 2 FAIL and ENG 2 START VALVE (FAULT?) We aborted the approach; remained at 3;000 feet and [notified ATC] and requested a pattern back to the ILS to provide time for ECAM and QRH actions and follow up.  I was pilot flying and remained so initially; Captain followed [the] non-normal methodology; had me continue to fly while he accomplished non-normal procedures.  After all ECAM; QRH and follow up actions were complete; including notification of ATC; flight attendants and operations he took over duties of pilot flying for the single engine landing.Initial evaluation by maintenance personnel indicated a fuel control failure; loss of fuel feed to the engine causing the rollback and loss of thrust. I would like to say that as a new hire (on IOE during this event) that the initial Airbus training program is excellent.  Every initial instructor; ground school instructor; simulator instructor/evaluator; and the IOE captains were wonderful to work with; expert in their areas; professional and personable.
While on ILS at 3000 FT; 180 KIAS CONF 2; and 5 miles from the FAF the following ECAM MSG showed up. 'ENG 2 FUEL CTL FAULT'; with an additional message 'avoid rapid THR LVR changes'. 15 seconds later ECAM 'ENG 2FAIL' appeared and ENG 2 rolled back.Aborted approach remained at 3000 FT and RWY heading. [Notified] ATC due to engine failure and requested vectors back to the ILS with a long final to complete checklists. FO retained aircraft control; while I completed all ECAMS; QRH follow-up items and the EMERGENCY checklist in QRH. Did discharge fire bottle #1 on the engine for suspected damage and possible fuel leak. After I completed the checklists took control of aircraft for single engine landing.
A321 flight crew experiences an engine failure at 3;000 feet during approach and elects to go-around to perform ECAM actions and QRH procedures. The Captain takes control of the aircraft for the single engine approach and landing. ECAM had annunciated 'ENG 2 FUEL CTL FAULT'; just before the engine rolled back.
