2000 Accord V6 stalls after starting

My 2000 Honda Accord V6 Auto trans, with 83K miles stalls right after I start the car, but this will only happen when my car had been idling before I turn it off, then return to the car about 10 minutes later to turn it on. The car will start without a problem, but then the RPM will drop and the car will stall. When I have this problem I found that if I let it sit for another 15 minutes it will start up fine and not stall. If I do not idle the car and turn it off right after driving, I do not have this starting problem. The Check Engine Light is not on. I have changed the Idle Air Control, the EGR was replaced about 10K miles ago, there is a new transmission about 2K miles ago. Any Ideas? Thanks
