Narrative:
Aircraft had experienced loss of left eec and left engine limiter at approximately 2 hours and 30 mins into flight (50 NM north of msp) from sfo to ewr. QRH followed, engine parameters remained normal, ACARS to maintenance control and received clearance to continue to ewr. On the shaff STAR, as the aircraft leveled off at 7000 ft, and power increased to maintain 250 KTS, the left engine did not advance, but instead suffered 3 distinct compressor stalls. The generator tripped off, the EPR read 0.98, egt 700 degrees, N1, 20%. The APU was immediately started to restore items lost due to loss of generator. Emergency was declared with 181 souls onboard and 22200 pounds of fuel. Engine failure checklist initiated, engine fuel switch moved to cutoff only after advancing throttle full travel and observing no response from engine, verifying that the engine had failed. Single engine landing accomplished after fully following published single engine inoperative approach and landing QRH procedures. Following day, maintenance verified a low speed stall and failures of eec, elc, and bleed valve control unit.

Title: B757 CREW RPTED THAT THE #1 ENG STALLED AND WOULD NOT RESPOND TO ANY THRUST LEVER SETTINGS.
Narrative: ACFT HAD EXPERIENCED LOSS OF L EEC AND L ENG LIMITER AT APPROX 2 HRS AND 30 MINS INTO FLT (50 NM N OF MSP) FROM SFO TO EWR. QRH FOLLOWED, ENG PARAMETERS REMAINED NORMAL, ACARS TO MAINT CTL AND RECEIVED CLRNC TO CONTINUE TO EWR. ON THE SHAFF STAR, AS THE ACFT LEVELED OFF AT 7000 FT, AND PWR INCREASED TO MAINTAIN 250 KTS, THE L ENG DID NOT ADVANCE, BUT INSTEAD SUFFERED 3 DISTINCT COMPRESSOR STALLS. THE GENERATOR TRIPPED OFF, THE EPR READ 0.98, EGT 700 DEGS, N1, 20%. THE APU WAS IMMEDIATELY STARTED TO RESTORE ITEMS LOST DUE TO LOSS OF GENERATOR. EMER WAS DECLARED WITH 181 SOULS ONBOARD AND 22200 LBS OF FUEL. ENG FAILURE CHKLIST INITIATED, ENG FUEL SWITCH MOVED TO CUTOFF ONLY AFTER ADVANCING THROTTLE FULL TRAVEL AND OBSERVING NO RESPONSE FROM ENG, VERIFYING THAT THE ENG HAD FAILED. SINGLE ENG LNDG ACCOMPLISHED AFTER FULLY FOLLOWING PUBLISHED SINGLE ENG INOP APCH AND LNDG QRH PROCS. FOLLOWING DAY, MAINT VERIFIED A LOW SPD STALL AND FAILURES OF EEC, ELC, AND BLEED VALVE CTL UNIT.
