97 Olds 88 - PLEASE Help!!!

I own a 97 Olds 88. About a week ago the airbag light came on. The anti-lock brake light comes on occasionally, and once in a while the brakes go all wacky. Last night while driving, my car died. It will turn over, but almost never start. On the rare occasion that it does start, it only runs for about 30 seconds before stalling. The drivers power seat no longer works. The power windows only work for the few seconds that the car is running. PLEASE help!!!

I don't know about the airbag light as mine didn't have this, but I had the same problem on the same year car. There is a splice under the carpet by the driver side door that goes to the ground (which is in front of the drivers side door with a threaded post and a nut). The windows, seat and the fuel pump all run through that splice and ground. I screwed a couple pieces of wire to the splice with self tapping screws and ran it to the ground OVER the carpet. My problems went away with this. My pad under the carpet was damp and probably ruined the ground. You have to take off the trim around the door to get the carpet up but it is really no big deal.
