It's going to be fuel, air, spark, or control... So I guess a starting point is - what have you changed recently and what have you already checked? I had a Honda do this to me a few years ago and after running everything down, it was a faulty ECU.

immediate loss of power while driving and when you at a light/traffic or parked it sometimes shuts off

Electrical bug...

Willing to bet you replaced the alternator and you had another issue with the charging system.

Your video would not come up for me.

Mileage on car?

When it stalls, does it start right up nice and easy or does it take some cranking?

Does it feel like and electrical issue or an engine issue?

What does fuel pressure look like - I had one recently where the fuel hoses inside the tank were failing and caused a similar result.

If it is an IACV you can tell by what duty cycle % it is operating at.

Sounds like something in the ignition system is worn or loose....

after you check all of that, look at the park neutral switch. they can cause these issues also.

True - I've had this happen when the ignition switch fails but it also includes not wanting to start.
