Car keeps stalling

What is your question?

I have a 2011 hyundai sonata and while driving on the highway my car stalled on me. I safely pulled over to the side and tried to turn the car back on and turned on. Once I got home I parked the car and the next day the car did not turn on. Now today I he car randomly turned back on without a jump. I am super convinced that the car does not need a new battery or a jump. Just not sure what could be wrong with the car.

What makes this problem better or worse?
