Hi,
All the codes except the P2394 are related to an ignition burn time. Code P2394 isn't indicated for this specific vehicle, but I do know it is a Chrysler code that is related to camshaft timing being retarded.
If PCM detects that the secondary ignition burn time is incorrect, too short, or not present, an error is detected. So, where to start?
Here is what I need you to do. The first thing I need you to check is if spark is lost when the engine will not restart.
Here is a link that explains how that is done:

If there is spark, we need to check the fuel pressure.

Please understand I am trying to go after the easier things first. The issue could be the result of several things. For example, if the timing chain is stretched, it can cause this to happen. That is a bit more involved. LOL Also, the powertrain control module can be failing as well.
Let me know how comfortable you are with performing diagnosing electrical issues. I have diagnostics for each of the other codes, but they are all the same procedure for each other than pin connectors.
Take care and let me know what you find.
Joe
