Hello,

You might want to check the fuel pressure regulator.
If it is faulty it can cut of in a similar way.
First test the fuel pressure.
You should have 55-62 PSI of fuel pressure with the key on and engine off.

Here is a guide on how to check fuel pressure:

I have attached diagrams for your reference.

Please let me know of any questions.

Thank you.
