Hi,
did you reuse the power steering pressure switch mounted to the pump, or did you install a new or did the new pump come with one?

HI,
There are 2 possible causes - faulty power steering pressure switch or bad rack and pinion. It takes special pressure gages to test the pressure to see which is bad, so unless you have this or want to spend $400 for one, my suggestion is to start with replacing the switch as it is fairly inexpensive- $30.
If still having the issue, then replace the rack and pinion unit

I was @ hwy. Speed and heard the power steering start making noise and could feel it in steering wheel then heard and felt a thunk and it was manual steering after that

HI,
Sorry for the delay. We are in the middle of severe storms and my internet is hit and miss since I have satellite internet.
Ok, those symptoms pretty much eliminate the switch and confirm that it is the rack and pinion unit
