    Hey guys, I have a 04 dodge diesel and it's only happened twice to me but the truck loses all power after plowing 10-15hrs. Both times it hapened when it wasn't that cold out. When I would give it more fuel it felt like it was bogging, and would up shift quickly. I checked all the guages but everything looked good. Took the truck to the shop and let it sit, ran like new next morning. Any ideas?

    It's a Cummins. Do you change your fuel filter regularly? Also, try running fuel treatments through the system regularly.

    I thought CumminGs was the high performance designation and Cummins is just the normal truck? :D:gunsfiring:

    I thought fuel filter also but it would cause problems when it's cold and not so much when it's warm. If the check engine light isn't coming on it has to be something simple...perhaps just poor quality fuel (low cetane).

    Hey...when is the last time you changed your air filter? That thing might be plugged up and you don't even know it.

    Last time I changed mine I couldn't believe how dirty it was. Bugs, feathers, leaves, ect...

    I change the fuel filter with every oil change anyway. I also always have a spare (and the tools required to change it) with me.

    id start with fuel filter air filter and some good quality fuel treatment. I bet it will take care of your issues.

    whats your temp gauge at when u feel power loss ? my cummins runs its best when i keep my winter cover on and let it toast at about 190 deg ( half way on the factory temp gauge )

    some ideas

    My one truck had a similar problem about a year back, turned out to be a bad battery. Might be something you want to look into. We could never figure out why but it did make sence after we realised how much juice we were drawing with lights, plow, sander ect.

    This year the alternator went.

    I would run lucus fuel treatment thru your truck, I run it in every tank. Lucas Cleans injectors, and increased my mileage and peppyness. Also you could check for codes when you lose power. put the key in, on off on off on, do not start, look at the dash and you should see any codes listed where your mileage is. stuff like P0XXX or done and that means you have none.

    There is also an APPS reset it is called. That was something that was recomended to me once and it fixed a hesitation I was getting. You disconnect the batteries, and leave unhooked for about 3 hours, then hook up, turn the key on and press the pedal slowly down and let it go slowly back up, then start. I am pretty sure that was it. I can look it up if you want me to just try the other things first.

    The truck was running at normal operating temp. I change the air filter and fuel filter with every oil change and run fuel treatment regularly but if it happends again I will check for the saturated air filter. I've already saved this thread so I can refer to it if it happends again. Thanks so much for all the help guys!
