Similiar to yours mine struggles to reach idle, gets rough, then dies. Without giving it some gas, it would take at least 3 tries to get the car to idle without dying. So when that happens, I tap the throttle a bit to keep it from struggling and it's fine. It doesn't matter what temperature it is.
I think for awhile people called it a "hot start" issue in which the car wouldn't start after shutting it off. Mine would do this regardless of temperature - even when it's cold.
