i was driving my 2008 malibu leaving a parking lot at almost 15 to 20 mph when my engine light illuminated and a few sec later car stalled off and on switch try to start no sound nothing car power was on (radio, a/c ). after 3 to 4 tries car started . i checked the code (ecm) cleared was ok for 6 days same thing happened again. i need help where to look since ECM they don't go bad easly.

This was a very common problem
