1993 cutless supreme, stalls out after driving approx 5 minutes in morning, restarts then fine.

There may be a O2 sensor starting to go bad, and also the Mass Air Flow Sensor may need to be cleaned. This requires a spray cleaner designated just for the MAF sensor. Also it wouldn't hurt to clean the throttle body with carburetor cleaner.

The starting/moving the steering column thing is a separate issue. That is a common problem in cars of that era. There were some issues with wires breaking at the connectors at the bottom of the steering column. They can be tough to find. If you're doing it yourself do some more research so you know what you're looking for and then be patient. If you're paying someone, try to find a mechanic who's been doing this for a while and has worked on these cars when they were experiencing these problems 10 or 15 years ago. Someone like that will likely know where to look and will go right to the problem. My guy did when I had my '95 Bonneville.
