It could be loss of fuel pressure, or spark. Does it just die like someone shut the key off, or stutter and slowly die.

A couple of things possible are, the ISC is always seeing the throttle at rest. So with increasing rpm, the pushrod is retracting all the way, and when you release the throttle it goes all the way to the stop, and closes the blade. That could be the case for either the 4.9 or 4.6 northstar. If it is a 4.9 car, it could have a failing ignition control module, causing a loss of spark or injector pulse. Does it only stall after a coasting event, when the throttle is released?
