No low speed power steering

I have a 1998 D1 that has little to no power steering at idle. Well, let me correct that. When the car is cold, the power steering works beautifully at idle and at all other speeds. After 10 minutes or so of driving, the low speed power steering goes away. The slightest tap on the gas though will restore it. Basically any rpm over idle has flawless power steering at all times, cold or hot.

I'm assuming this would be indicative of a pump issue, but it would seem isolated to the control valve. Are there any options for repairing or rebuilding the part of the pump specific to providing extra pressure at idle?

Is there anything else I should consider or trouble shoot first? The problem seems so specific and isolated, I just don't want to miss a solution simpler than replacing the pump.

The Serpentine belt has 70k on it and is starting to show some minor cracking. I would think if the belt was the issue, the symptom would occur as soon as the car started and not just after the car warmed up, though.

The car has 150k+ on it, as far as I know the pump is original, although I bought the car with 85k on, so I'm not sure.

All the power steering hoses were replaced a few months ago, which is actually when this symptom began. I'm not sure why new hoses would have caused this to suddenly occur, but maybe someone else has an idea. I just replaced the box, because it had some major leaks in it, although I never let the fluid level get low in the reservoir.

Thanks for any help.
