Periodic rough idle when warm

My 95 4.0 has had a periodic idle issue for quite a while. It seems it may be getting worse. Here is when it only may happen:

Vehicle is fully warm. I shut it off for about 1 hr or so and when I restart it, it shakes and misses in idle. It will idle fine after I drive it around or if I rev the engine for a while when still parked.
This never triggers the "check engine light".

New fuel filter, plugs and wires.

Any ideas?

I am currently having the same problem on mine, Have you had any luck fixing?
I'm thinking possibly fuel pump malfunctioning
also no codes, and the air intake gaskets are all tight, MAF sensor is clean
