No Power Steering

I have a 2014 Q50, and the past few weeks my power steering has become really groany and slightly heavier. Today we got some heavy rains so I did a couple donuts, and afterward I had no power steering at all unless driving around 10+ mph. (yeah yeah, spinny spinny = breaky) but my fluid has been fine, and still fine throughout, also flushed by nissan a few months ago.

Is this my power steering pump going out and I killed it? Or is this a potentially bigger issue?
