Is the Immobilizer (small car icon) light flashing on the dash when this happens.
If so, you're key is going bad and the security system is not recognizing it.
Another possibility is a dirty throttle body. If it gets too dirty the computer won't be able to open it up enough to hold an idle. If this is the case it should be carefully cleaned and then the throttle body has to be adapted using a factory scan tool.
