It's hard to say with so many possible things it could be. It sounds like it is more or less stationary now, unless you can drive a straight line around your block. The engine cutting off is something electrical, probably fuel or spark (ignition) related. The steering wheel would immediately lose power steering when the engine stops, but it shouldn't lock. That would be a key cylinder and ignition switch problem. If the key is still on, it should not "lock" the steering wheel.
I believe you should let a competent mechanic diagnose it, beginning with some basic voltage tests, and progressing to a scanning tool to actually watch live streaming data in and out of the engine computer, or powertrain control module-PCM. Two things I would do even before taking it to a shop or mechanic is to have the fuel pressure checked and have the pcm scanned for possible trouble codes. Actual codes or pending codes could indicate where to start looking. And a fuel pressure test tells you if fuel at the correct pressure is getting to the engine, to the injectors there. I know Autozone will do the scans for free, and I think you can get a free fuel pressure test there under their loan-a-tool program. You may know a friend or relative with a fuel pressure gauge, maybe even a scanner or code reader-all the better! Good luck.
