I have a 88 YJ/2.5, when first starting it will idle around 2,000 rpm for about 10 sec. then die. It will run if you give it gas but it runs rough(spits and spudders). While driving it will run rough then clear up for maybe 30 secs. then do the same thing. Any ideas of what you all think it may be.
I have had a couple people tell me throttle postioning sensor....

Could be any number of things because it's got all kinds of sensors on it...i would try TPS sensor (above mentioned) and maybe an Oxygen sensor

You could check for a vacuum leak. I had that happen once on an older vehicle once.

or MAP sensor. My vacuum line came off the map sensor and it did the same thing.
