Loss of power steering

[THANKS]

Sup, E38 drivers. Got an problem with a loss of power steering. When driving at moderate speed it's okay, but a soon as it goes up in rpm, it becomes stiff. I also notice if I'm in park and rev the engine power steering is lost as well. Need to get this fixed soon as possible. I tend to forget about until I'm taking a corner aggressively

Is it leaking? If there is a major leak in the high pressure hose, it will lose pressure under load, but have enough at idle.

There is a leak. Not sure where its coming from. I thinks is leaking on my alternator very slowly causing it to screech on start-up. Both lines to the power steering reservoire are moist from ATF. Which one is the high pressure hose?

Interesting, I get a screetch at start up most days now (like I did last summer) and assumed it was just my PS pump going. I replaced the alternator last year because of the screetching, never thought it could be the PS fluid causing it. HMM.
