If it starts up w/o cycling the key, then I would imagine it could be something as simple as the IAC wiring or the IAC itself. When the IAC goes open, it shuts, which would shut off all air assuming you're off the throttle. Are you off the throttle, or was it open throttle when it died?

when the car shut off on my i was just cruising in 4th gear... but as far as the hanging idle im completely off the gas and it shows 4-6 throttle %... on the IAC does it matter which way it goes in? like with the plug on the sensor pointin up or down... cuz on my 62mm throttle body it has 2 holes but the IAC has only one on it where it bolts to the tb

While the car is shut off, remove the cold pipe from the throttle body. Then start it up, and put your finger over the IAC passage inside the throttle body. @ idle the only way air can get in is through that passage. If you cover it, the car should die. If it doesn't, you know you have to look for a vacuum leak.
