OK, it's stalling, and you want to take it on a 450 mile road trip??
Actually, watching the video, I think your IAC is crudded up and reacting slowly. Does it only do this after you rev it?

When you go to restart it, does it help to step on the throttle? IOW, does it start more quickly with some throttle applied? Or not?
Can you remove the air cleaner and hand throttle it and watch what the injectors are doing?
I agree that it's not the Crank Sensor...since the car doesn't have one.
I agree that it COULD be the IAC's.

O.K. That helps me help you. I think it's flooding after it comes out of decel/enleament mode.
Check/clean your IAC passages. Check your fuel pressure. Should be 9-14 PSI. Most like it closer to the 14 number.

I would do all of the above, then balance the throttle bodies, and reset the TPS. All normal maintenance on a Crossfire.
