Here is what I have done so far:
1. Replaced the power steering pump
2. Replaced the pressure switch on the power steering pump.
3. Replaced the power steering control module behind the glovebox.

Not sure what is left that I can try? Anyone else run into this before. Wiring looks fine( 2012 370z sport). No leaks of power steering fluid. So weird how sometimes it comes on and then sometimes it totally shuts the power steering off and its hard as F to turn the car.
