Beaucoup possible reasons from bad gas to poor maintenance. Starting point is CEL codes.
Other info we would like:
Engine
Transmission
Mileage
1500 or 2500 series

My guess, you have a 5.3 with automatic.

Dirty fuel filter, engine air filter, or clogged cat could cause that. As mentioned above, there are many other possibilities. Is the symptom worse in certain situations, like when the engine coolant is cold?

There might be a problem with the accelerator pedal position sensor.
