Default 2000 Dodge Ram 1500 2WD Laramie Extended Can P1391

Just got back from getting truck inspected and coming up the hill it stalled out. Ran perfectly fine up to that point then had to have pulled up hill onto level ground.

Now it will run and idle but as soon as it is pit onto gear it will stutter and misfire and sometimes stall out before even attempting to move, it is throwing a P1391 error code that I have cleared a couple times to make sure.

Took a recording of what it's doing and if anyone has a more narrowed down idea at what could be the problem for it it would be greatly appreciated as I've read that code can be many things from CPS/CKS to something with the A/C.

Video of what it's doing: https://youtu.be/BbqWOJcsaQo

Sounds like your crank sensor is bad - please replace it with a Mopar branded crank sensor, as the aftermarket sensors don't tend to be made anywhere near as well.

Update.
I bought Mopar sensor but haven't had time to put it in yet but I have noticed that when the truck is cold it will ring just fine it's when it gets up to temperature that these symptoms start to happen.

Would this still be the sensors fault or another thing I should look into getting?

Something is getting warm, and failing. Unfortunately, there are a whole selection of parts that can cause that.... but, given the code you are getting, gotta be cam or crank sensor.

Update: The crankshaft position sensor had small cracks in it when removed and now that a new one is in its place the truck runs like a new one again.
Thank you everyone that responded to help confirm this was what was wrong with it.
