I have a feeling you lost fuel pressure due to a faulty fuel pump. What you need to start with is this. First, see if it starts for a couple of seconds using starting fluid. If it does, then stalls, we know it is a fuel-related issue.
Or, here is a link that shows in general how fuel pressure is tested:
Since it stutters like it is trying to start, I don't think it is ignition-related. However, if it doesn't start with starting fluid for a couple of seconds, here is a link that explains how to check for ignition spark:
Here are directions specific to your vehicle for testing fuel pressure. Note this is for a 2.7L You indicated it is a 3.7 and that doesn't exist. It's either a 2.7, a 3.5, or a 5.7. If I got the wrong engine, let me know.
Let me know what you find or if you have other questions.
Take care and God Bless,
