Drove the E at night to the market, when i started the car the abs and airbag lights remained on then dashboard lights started to arbitrarily come on, radio disconnected (no power at all), then dashboard started flashing. I pulled over and turned off the car. I tried to start it and cranked slow with all the lights fluctuating. I got a jump and drove a 1/4 mile before the lights dimmed and the car sputtering and lost all electricity it then died altogether. Alternator and battery replaced (battery checked 2 weeks before & fine) $600! 5 days later the whole thing started again. I was able to get home before the car shut down. Anybody have any ideas on this?
