Help! What could be wrong with my 2001 Dodge Truck?

I have a 2001 Dodge Dually truck. It is a 3500 4 X 4. 5.9 Turbo Diesel Engine.

Here is the problem. When you are driving at around 30 to 35 miles per hour it starts missing. It just hesitates for a little. When you accelerate up to about 50 it will stop most of the time. We also pull a 12,000 pound trailer with the truck and it will also do this while we are pulling it and have the overdrive shut off.

However, when my husband unhooks all the battery cables from everything and waits a couple of minutes and then hooks them back up, it stops doing it for a while. Then after about 100 to 200 miles later it will start to do it again. What could be causing this? We had a new injector pump and fuel pump put on it less than two years ago.

Help!
