Have you checked the Crankshsft Position Sensor?
It can shut off power to the ignition system.
My car had a problem very similar to yours. Engine stalled, could restart in 5-15 minutes, no check engine light, no malfunction codes from the computer. The only indication was that the Battery would show in the message center. The problem went away when the ssensor was replaced.
