Not sure if I'm in the right place. I have a 2016 Chevy Malibu. Without warning I was sitting at a stop light and my engine power reduced light came on. The engine shut off but the radio, lights, dash lights etc kept working. I let it set for several minutes and tried again and it started and I drove home. No more warnings came up. Any suggestions?

 

This is a site for chevy cobalts. the malibu uses a LTG engine. better off joining an LTG forum.
