I have the car listed above and it shuts off when I start it warm and won't hold idle in park if I don't rev it will eventually hold idle after revving but it will drive fine in any other gear?

This sounds like the fuel pressure sensor could be going out, do you have any codes? You can get a CAN scanner from Amazon for about $30.00.

Here is a video to show you how:

Also, we should check for vacuum leaks when the engine is cold, this guide can help:

Please run down these guides and report back.

Someone on the Lincoln forums told me he had the same problem, he said it was the fuel filter, it gets clogged if you fill up right after the fuel tanker refills the gas station, he says it stirs up sediment and will clog a fuel filter.
