Could the fluid be contaminated, is it the right one? obstructions? ---

The problem probably is with the rack and pinion. Just to be sure, have a mechanic check the high pressure when there is no assist. If the pressure is low when assist is commanded, check the pump to see if it will produce full pressure. If the pump is okey, a pressure seal in the rack is leaking until it expands with the hotter fluid and seals again. A rack replacement is usually in order. ---

The is a TSB out for this problem. The filter screen in the reservoir clogs. The fix is to replace the reservoir and replace the fluid. It uses ATF+4. Just replacing the fluid may do the trick.
