van looses all power after about a mile & will not rev, turn engine off wait about 1min & will run ok for a short distance. no fault codes, looking at presures on dataloger desired & actual presures match, air flow signel as expected, fuel presure test between filter & pump 0.2 bar restrict supply & will raise to 0.8 bar replaced fuel filter for the sake of it.
any ideas would be helpfull.
