I am also having the same symptoms. I replaced the plugs, rotor, distributor cap and fuel filter. The car ran for a few miles and died. I purchased a new distributor friday and installed it. The car fired up and ran for 5 miles and then died. The car will start and turns off immediately. Need to get it towed now. Please post how you fixed.
I have 11 and 45 as trouble codes also. When the car won't start the coil does have spark, but the distributor does not. Not sure if I have a new but defective distributor, or its the ECM as you suspect.
