Pontiac grand am 2003 stalls while running

[cundango1]

I need help. My 2003 Pontiac Grand Am stalls while running. It doesn't make any noise it just stops running. After a while I can start it up again. I took it to the dealer and it doesn't stall for them so they can't find anything wrong. What has already been replaced: Coil, cranshift sensor, spark plugs, fuel filter. Any ideas on what can I do?

A no-code stall? I'd check power first, the PCM can't tell the difference between turning the key off and a loss of signal.
