Could be a number of reasons.. you could be losing compression, you could have a clogged diesel particulate filter (if so equipped), worn components... you'd need have have it inspected to narrow down the cause.

There are many reasons as to why a car may lose power while driving. However, the most likely cause is a bad fuel pump. This causes the car to 'think' that there is not any gas, so it begins to stall, and eventually stalls while driving.
A dodge pickup 1500 would stall out while driving because of a defective air filter.
