What would cause a momentary loss of power steering?
Hydraulic Pump Valve Blockage Hydraulic fluid that is old, has lost its lubricating and cooling properties or is contaminated can cause an intermittent power steering loss. Dirty pressure valves inside the pump can momentarily freeze or become clogged, disallowing enough pressure to turn the steering rack gear.
Does loss of power steering mean complete loss of steering?

If the fluid feels gritty between the fingers, it means rust, metal shavings and dirt has entered the reservoir.
Can no power steering fluid cause noise?
