Few questions. Any codes? When is the last time you changed the air filter, oil, spark plugs? Or cleaned the TB and IAC?

Other items can be clogged CATs, bad O2 sensors or bad TPS.
To check the Cats remove the O2sensors on the manifolds. If power comes back and sputtering stops the CAT s are clogged.

Can also be a bad coil... They tend to act up when they heat up.

Like asked already are there any check engine lights? If so what is the light doing? If it's steady you need to get the code. If it's flashing that means you have a misfire and most likely need new ignition coils. 2006 shouldn't be having heat sink issues. Does this behavior progress to the point the jeep is unusable? If so it may be a PCM. Also depending on the code the TPS goes bad in those often. Answer those questions and I will try to help further.
