My vehicle listed above XL model traction control and engine light came on at same time followed by reduced engine power. The car then slowly stalled and would not start. After a few minutes it started again, and the same thing happened after driving a little.

Yep, this can happen when the throttle body needs to be serviced because the car goes into limp mode. This guide should be able to tell you more and I have included a video on how to fix the problem, make sure to clear the codes once the service is completed.
