My truck turns on after the third time starting it then runs for about 5 minutes after that it begins to tremble and sounds like its trying to stay on then shuts off any suggestions on what it might be? How can i determine if it is a problem with the fuel pressure regulator, fuel pump or sensor? Thank you for your time

Any check engine light? Did this happen suddenly or is it a problem that’s ongoing and has got worse and to this point?
No check engine light. This happened about two weeks ago and I haven’t been able to use it since then.

Correct, I looked it up for you.
Minimum is 30 psi, maximum is 65 psi

Yep to low to run.see if there is a external fuel filter
to change.If you have low fuel pressure it can cause all kinds of problems, including the ones you’re experiencing. More information on diagnosing performance issues, including fuel psi regulator problems can be found here.
