Stuttering in 4th and 5th gear

Hey everyone!

So here's my issue:

I drive a 92 4.0L Wrangler and recently it's started "stalling" momentarily when I'm at speed - usually around 60-65 MPH. It feels like it's running out of gas, will start to "chug" a bit and stutter like it's not getting any to the engine, but will pretty much immediately pick back up and run fine. Some trips (regardless of time spent actually driving) this won't happen at all while other days it will happen 4-5 times during a 20 minute drive.

I just wanted to crowd source some opinions before I start diving into (and tearing apart) my beautiful baby this weekend, so if anyone has any suggestions on what may be wrong or where to start looking I'm all ears.

Thanks in advance!

Start with the obvious, replace the fuel filter. How long since tuned-including replacing plugs, cap, rotor, etc. Does temp seem to affect when it will do it?

Any check engine lights? Along with a basic tune up check for a good connection at the ecm/ecu.
