I have a 95', 4x4, 5-speed, 4.0l with 308,xxx miles

- I start the truck cold, it starts up and runs smooth.
- if I run it for a while, shut it off, and restart it shortly after it still runs fine
- if I run it for a while, shut it off, and restart it 15-40 minutes later it kind of pops and lopes but clears up after no more then 30 seconds of running

* I replaced the fuel pump and filter
* I checked compression and it's even across the board
* no codes have been thrown

It also idles high on start up for a little bit then idles kind of low once warm. Any help would be greatly appreciated
