    Truck runs good for about 10 minutes then loses power/boost, stop, shut off, restart and repeat! Truck is 2014 pro star with N13 in it! Thanks for any suggestions!,,

    Those codes are all fuel pressure exceeding commanded. Failed fuel pump or restricted return line. 99% it is a bad pump.

    Kind of sounds like a possible collapsing fuel line.
