CEL and power steering…

Recently on my 14, my CEL came on, and the ps started acting screwy. When I am at a stop, the ps works, but the CEL light is on. As I start to drive, the CEL goes off, but the ps quits working?!?
I charged the batteries, thinking maybe it was a weak battery even tho my buggy is 8mo old, and my second battery is brand new. Also disconnected them to do a hard reset, but that didn’t work either.
Any ideas what the problem may be?

Cliff notes…sitting still, I have powersteering and CEL is on, driving CEL goes off and ps quits working.
