This could be a number of things. When you put the vehicle in gear the transmission is adding a load to the engine and if the air/fuel mixture is off then it will not get enough fuel and will stall.
This is usually one of three things. A dirty/faulty idle control valve, faulty o2 sensors, or even restricted injectors.
You engine uses an electronic throttle body to control idle so I would suggest with cleaning that first.
If that doesn't solve the issue then I we need to look at the PCM data with a scan tool and see what the o2 sensors are doing when this happens. I imagine they will tell us that the exhaust is lean which means the injectors are not delivering enough fuel.
Let's start with that and go from there.
