Car is a little slow starting in the morning. But on occasionally it will stumble and shut off. It did get a check engine light once. The Ford dealer told me it was the pressure switch on the fuel rail. I changed that still have the same problem. A private owned shopped looked at did scans, drove hooked up to a laptop couldn't find any problem. When it shuts off in just a few minutes it will fire back up and drive fine. On the couple of accusation it light the light. After driving it the light resets.

If the light came on, there should be codes. Since it is slow starting in the morning, it sounds like a fuel pressure related issue. That is where I would start.

I need you to check fuel pressure to confirm it is within the manufacturer's specs. Here is a link showing how it's done:

The attached pic shows pressure specs for this vehicle.

Let me know what you find.
