Do you have a check engine light on? First thing I would do is unplug the IAC motor when the engine is warm. If the idle speed doesn't change you have a vacuum leak or a bad IAC motor. If the idle speed goes down you might have a bad TPS or IAC
if the battery is ok why do you need to jump anyway? most likely its not ok, the alternator do not provide enough power at idle to supply the engine the amount of power needed to keep it running,below 1200rpm you actually use the battery, in the range of 1400 to 2000rpm the alternator will produce a surplus enough to recharge the battery, but if the battery is old it does not recharge enough to start your truck
Faulty oxygen sensor or low fuel pressure can also cause these codes to be set. I'd go for a fuel pressure test when acting up if at all possible just to confirm I have pressure needed. Have heard of coil problems as well. Should be a good blue 1" min. spark from coil.
