Idling up and shutting off?

Can you give a little more detail on what is happening? Does this happen when you first start the vehicle or is this while driving?

Here are some guides on stalling at idle as that is what I am assuming:

If this is happening when it first starts, then we need to check the fuel pressure while this is happening and that will help figure out if that is the issue.

Let's start with this and go from there as I am sure this info will get us a better idea on next steps. Thanks
