Narrative:

Cleared for takeoff on runway 8R, advanced power to a reduced takeoff power setting as per tps (thrust performance system) data. Almost immediately the left engine failed for no obvious reason. Initiated an abort at approximately 40-50 KIAS, cleared the runway, returned to the gate and the aircraft was taken OTS.
