I had an odd experience. On a cold (near-freezing) and very wet morning with a only a slight warm up I tried to turn make a right turn in my 2002 Mazda B4000 after a complete stop. While slightly rolling forward I turned the wheel and it turned one half revolution and stopped, like it normally would after 1.5 revolutions, as if it had hit the end of the rotation. It was enough to complete the turn, but I quickly exited into a parking lot. In the lot I tried full hard left and right turns without a problem. Then I ended up driving through a deep puddle to exit the lot, and upon trying to make the turn back on to the road the same thing happened, again with a right turn. Two minutes later at the next turn out I again had no problem. Is this as simple as wet and cold slipping belt on the power steering pump? Would that cause the steering wheel to lock up like that or would it just make it harder to turn?

Re: B4000 steering stopped in mid turn.
Your belt could be the culprit i had the same problem with my old ranger where the belt sliped under certain conditions and causes loss of power steering pump pressure.
the next time it happens pull the whell as hard as you can and se if it acts the same as when the vechile is turned off

every possibility that the stop leak increased the viscosity and the leaking hose could not handle the extra pressure in cold weather
Additives are really a waste of time as it is a stop measure that could have cost you a life when calling into a steering shop would have taken 1 hour and fixed the problem
I had this same problem and the dealer could not reproduce the noise when I would take it in to get looked at. (during the day when the temperature was warm) So I decided to leave it over night and they test drove it in the morning when the temperature was cold and they heard the noise. It ended up bing the steering rack.
What do you mean by stick? It doesn't turn at all or it is just harder to turn?
Also how cold? Posting your question in May, I don't think you mean freezing winter cold unless you live in the southern hemisphere.
For freezing cold temperatures, it is not uncommen to get harder steering especially if you have old contaminated power steering fuild. At freezing cold temperature, power steering fluids gains vescosity and it is harder for the pump to circulate it, but the problem should go away as the engine warms up. I would suggest that you replace you fluid with a fresh approved one.
this sounds like an issue with the power steering rack and pinion unit, poss one of the internal O ring seals leaks when cold, try using LUCAS oils power steering conditioner, it is the only one I know of that really works, also I would recommend you flush the power steering fluid before you add this product.

To me, it sounds like your problem is "morning sickness". The problem is there only after the vehicle sits for a period of a few hours (overnight) and then is gone once the vehicle warms up some.
What happens with "morning sickness" is this: there are nylon rings in the pinion section of the steering rack and pinion. Over time, these nylon rings wear grooves into the aluminum housing in which they reside. When the steering rack and pinion is cold, the pressurized power steering fluid can move past these rings causing difficulty in steering or an unsmooth steering condition. Once the fluid warms up some, the nylon rings expand and seal the gap and fluid can't get past anymore and it stays where it's supposed to be, leading to the normal steering you experience the rest of the day.
The only repair for this condition is to replace the power steering rack and pinion. A used one can be a gamble as this could reoccur in a short time. A brand new one is overly expensive. That leaves a good quality aftermarked remanufactured rack and pinion as your best option. And be sure to have the vehicle aligned when that work is completed.
