Does it start and run? Or crank no start?

It does start and runs until it gets warm then it has a hard time starting until it cools back down while driving it just quits like it runs out of fuel but has 3/4 of a tank

What does your fuel pressure sensor read? Should have a high and low side sensor

Check that there aren't any melted pins at the fuel tank plug.
Getting involved in discussions because I have a lot to learn still.

P069E is just a road sign code to the Fuel Pump Control Module. P2635 is the code to follow for now.

Can your scan tool access the FPCM? Can you observe the actual fuel pressure and desired fuel pressure? What are the fuel pump trim values?
