2.5 randomly misses on highway

Ok so I have a weird issue. Took my jeep to work for the first time and noticed a odd and random issue.

In 5th gear jeep starts to miss badly causing the speed to drop fast. I down shift and problem goes away.
Shift back to 5th problem comes back.

Realized the problem only occurs when rpms are below 3k with a load.
If I'm crushing threw town it won't do it.
After awhile on the highway the problem will go away.

Any ideas guys? Thank you in advance

Mine will do the same thing in 5th. however it only does it without load. if I let off gas goin down hill and the rpm's drop to 1500 then it will miss/run very rough until I get on the gas. gonna seafoam it this week and see if that helps...
