Hi,
When this happens, does the vehicle lurch, or jump forward? When it is at idle, are you able to rev the engine normally while in park or neutral?
I'm trying to determine if it is an engine or transmission-related issue. If the torque converter clutch is always engaged, that will cause it to stall (but lurch) when placed in gear.
Let me know as much as you can. For example, does it happen regardless of temperature? Were any symptoms noticed prior to this happening? Will it continue to idle if left in park?
It would be a good idea to check the fluid level and condition. If it is dark then that points to a clutch issue which could support this idea.

Thanks for the reply.
It starts normally, it just shuts off when shifting into drive. No lurching, it just shuts off. There were no symptoms prior to this. Not sure about the temperature, I haven’t driven it since it started doing this. I will check the fluid.
Thank you

Hi,
Okay, that helps me. By chance, is the check engine light staying on when the engine is running? If so, have you had the computer scanned for codes? If so, let me know what they are.
As far as your description, it sounds like the engine idle speed is just low enough that the added load of placing it in gear causes it to stall. This, most commonly, is the result of an engine vacuum leak. Take a look through this link. It explains how to locate and repair a leak.

Next, the vehicle has what is called an idle air control valve (IAC). The IAC is what is responsible for maintaining the engine's idle speed. They can fail, get dirty, and the air inlet they seat in can become blocked.
The one on your vehicle is located on the throttle body near where the air inlet tube from the airbox connects. See pic 1.
If you are unable to find leaks in the vacuum hoses, you may want to remove, inspect, and service the IAC. Here is a link that explains how it's done:

Let me know what you find or if there is anything I can help with.
Take care,
