The power steering is on this vehicle is electronically assisted. Meaning it does not have a power steering pump. The electric motor could be going out, pulling too much current at times, and tripping the breaker. The best thing to do is take it to the dealer, and have them inspect it.

Hiya...
If you stand at the front of the Equinox's hood that's open, look at the bottom-right corner area behind the headlight area, the battery is 'hidden' underneath the black box-like part that you need to remove clips or screws to lift it up to gain access to the battery cover to reveal the battery sitting onto the battery tray.
It's one of the common thing most people wonder where the battery is located.
The battery is secured into place by a large bolt/black rectangular shaped part onto the battery tray...just unbolt it and you're ready to pull it out.

It sounds like the battery. It is possible you have a dead cell in your battery which will act like what you have described. Check your cables to ensure you don't have a grounded wire somewhere. Then have the battery tested at Auto Zone. If it is bad replace it. If it isn't bad then you will need to start looking for a short somewhere.
