Lose Power Steering problems of the 2016 Jeep Compass

While getting onto a highway, my rpms dropped and I temporarily lost power steering and started slowing down, then it "caught" and I was able to drive it straight to a car place to get the free diagnostics. Everything came back normal so I left. Later in the day as I was pulling out of my neighborhood it stalled again and completely shut off this time. When trying to turn it on again it either would but then would immediately stall again or it would just never start. While trying to turn it on, all the dash lights light up including check engine, which has not been on until the car stalled the second time.
