    you change the fuel filter recently? also check your ground/postive cables real well them side terminals are know to hold corrosion in them and spread down the cable till it wont pass any juice to were it needs to go

    well its a 6.5 turbo diesel, the biggest main most frusterating problem i had it on my old truck same problem as yours, is the PMD ( pump mount driver) failing, this causes an intermittent stalling of the truck, usually being able to re-start after a few seconds. sometimes with the case of mine if the PMD is really bad it gets so hot the truck will not restart, on your truck it should be located on the driver side of the injector pump, its the small black box with 4 torx bits holding it in place, you may have to pull the intake manifols to remove it, I know i had to lol. since there is no real way to test a PMD it is just better to replace it, since it is a main source of headaches on 6.5's. in my oopinion what i would do is buy the heath diesel PMD relocation kit costs about 500$ nut comes with a 7 year warranty, adn is way way better then a stock one becasue it moves it out of the engine bay so it wont overheat anymore. hope this is helpful in anyway
