Reduced Engine Power 2006 Pontiac Torrent

I just got new front Pontiac Torrent (front wheel drive)and a oil change. The next day the car after driving about 5 minutes warning lights reduced engine power and check engine light came on an then the car lost all power. I had to pull over and after panicking tried to start the car up and it started and was fine. The next day again it did it about 3 times but always starts up after a few seconds. Do you know what may be going on? Could it be related to the recent oil change or tires?
