Sounds very much like your P/Steering Fluid is contaminated.
Possibly condensation, or someone is playing tricks on you ?
I had a friend with a BMW, ask me for help, few weeks back.
He had put just a little brake fluid in by mistake, and it gave exactly your problem.
You will have to change the Power Steering Fluid in the system.
Good Luck !
