Did you check to see if you were maintain fuel pressure ? You could have a bad fuel pressure regulator or the fuel relay could be bad and as soon as it heats up it fails shutting the fuel off, let me know what happens and we can go from there.

I had a Ford F150 New at dealers, It did the same thing, come to find out the dealer had given me the wrong key, and the chip did not match the ignition system. Maybe your chip has malfunctioned.
