2013 Chevrolet Equinox turning off completely after starting

Please help!!! I am desperate. We just bought a used 2013 Chevy Equinox. Everything was going fine until three days after we bought it. It started shaking then completely turned off after I started to back out of a parking spot. That’s when it got worse… It has happened every day since. We got it two weeks ago. It turns off after idling for literally 10 seconds after I start it. We brought it to two different mechanics, no code shown. I read that the timing variable solenoids need to be replace…
