MN14

Last year, my power steering shut off while I was driving, 4 times in one day. A stabiltrack warning came on my dash. I checked all fluid levels and all seemed fine. Then for several months, no issues. All of a sudden, it started happening again. Now today, I could not start my 2016 Colorado. The anti theft light is now on. I was able to jump it to get moving again. I shut it down and let it sit for about 10 mind and it started up and the light was gone. Chevy dealerships have not been able to help. Any suggestions?
