My car listed above occasionally stalls out while driving but does not lose power. No check engine lights or codes coming up.

Does it restart right away or does it take some time?

Here is a guide that will help with this issue in more general terms:

However, with your vehicle being newer, I suspect we have a circuit issue with either the crank sensor or PCM power and ground.

If there are no codes or any sign of any issue and the engine just shuts off, I would just go ahead and replace the crank sensor as it is the most likely cause. If that does not solve it then we are going to need to monitor voltage of the PCM when this happens. Which means we are going to have to most likely set a meter up and run the wiring into the inside of the vehicle so you can see what it does whenever it acts up. This is not easy so hopefully the crank sensor fixes it.

Let me know if you have questions.

Okay. So when does it do this? You said while driving but does that mean at highway speeds or coming to a stop light? Sitting still? Making turns?
