Your symptoms do strike me as a failing check valve. Although reading your original post it seems there were occurrences of the sputter even when pressure was 40?
Have you tried the key-on--hold--start routine? If I suspect a check valve issue I do that to spin up the fuel pump and pressurize the lines, might do it two or 3 times before actually attempting to start. if that eases the symptom I'd feel pretty confident its a failing check valve.
sadly I dont know where the check valve is on the 2008.
