battery and brake light on,speedometer failed,engine sputtered, car won't start on 1997 Nissan Altima

I replaced my battery, then i thought it was the alternator. diving home from school my battery light and brake light would come on when i was under 2000 rpm. air bag light flashing. a mile away from home the speedometer stopped working. 700 feet from my house when my car stared to sputter, as if the engine was on then off over and over. power steering failed and i barely made it to my house when the car died.
