car sputters

My car starts up fine, but when I travel to next stop, turn off the car for 10-15 minutes, the next startup the cars runs rough , sputtering like its missing firing. after several hours in garage, it starts up fine again

If your car has mechanical fuel injection this could be a failed accumulator.

Thank you so much for this diagnose. Dealership game me full tuned up last year that has not solved this problem. Is this the same as fuel pressure regulators? I am have trouble finding accumulator for my car.

No, it is completely different.
