Based on the description, it sounds like you're on the right track. Update once you get the pump replaced.

I found my car did this when I bought it as well the pump was also super noisy because it had regular power steering fluid, I replaced it with ATF steering went back to normal and no more noise! Could also be a kink in one of your power steering lines

my son was driving the car when the steering came back. so i disconnect the twin orifice connector at rack. i believe system in in high speed mode? its been working like this for a couple weeks it has good steer feel i think we will leave it alone for now.
