Need help!

I have a 1999 Ram 1500 with a 5.2. The check engine light is not on. It will start up no problem it idles fine in park and in neutral but as soon as i put it in reverse, drive or any other gear. it shuts off almost instantly. I have no idea where to start with this problem. A friend of mine told me to replace the tps, i did and it didnt fix the problem. There are no leaks that i know about, and like i said the check engine light is not on. It just happened out of nowhere. If anyone might know what to do please let me know.

Maybe the air idle control valve (AIC). Check out the video.
