ENGINE QUITS SUDDENLY

1993 Cadillac Deville

Engine Performance problem
1993 Cadillac Deville V8 Front Wheel Drive Automatic 175000 miles

Engine will go dead even at 2500 rpm. I have replaced ignition wires, plugs, rotor, distributor cap and fuel filter. Can bad gas or moisture in gas tank cause this at such a high rpm even at fast idle. Egr valve replaced. Gas tank three-fourths full. Engine extremely smooth and hardly any vibration at any rpm. Transmission is excellent.

Pull the codes: off and warmer on the heater controls at the same time, with key in the on position.

Look in the mileage center for the codes, starts out 8.8.8 and ends with 0.7.0, write them down and post them here
