1997 Mercury Sable Random effects, what is the cause?

I hope I put this in the proper category, as I am only guessing that it is electrical. Here is what is happening:

My power steering quit working. There is no leak.
The next day my ABS light came on.
I also noticed my turn signals were not working inside the car. I was getting ready to check them outside, however, when I was pulling into a parking spot, my engine died on me. It would not restart.
When I tried to restart, I could hear the very quiet clicks of the starter trying to turn over.
The radio also was working after the car quit, so I assume it is not the alternator or battery.

But, I am not a car expert, so who am I to assume?

I really appreciate any help. This problem has me stumped.
