This could be one of two problems:
1 Weak or failing battery. The PCM can be sensitive to low battery voltage. With engine running battery voltage should be 14v plus or minus 0.2v A battery that is over 3 years old should be checked first.
2 IAC or idle speed motor. Located on back side of throttle body. I think it's held in with Torx head screws

The other guy is right. The first thing you need to check is your battery.

with the mileage and the truck u may have an 02 sensor going bad or maybe a vaccum leak. i have a 01 ram v6 and was having problems with the o2 sensor on it and it was flooding out not idling right and come to find out that the o2 sensor in front of the catt. converter actually sends signals to ur comp. and will adjust ur fuel to air mix and it keeps changing so u might run a diag.test on it to see if it pops up there is not really any need to worry about ur rear o2 because that one just regulates ur back backpressure.

Check battery voltage while engine is running. PCM can be sensitive to low battery voltage. Is the check engine light on? Auto Zone or Pep Boys will check codes for free.
