I just purchased a 2000 Rodeo LS 4x4 yesterday with 39k miles. It was turning over a little slow when i bought it, but i thought it was just battery related, it seems now that it is taking even longer to crank and will frequently cut itself back of if you dont rev the engine some as soon as it cranks. Sometimes, however rarely it will fire right up. What could be the problem here? I am out of bumper to bumper warranty but still have some powertrain left, but im doubting this is power train related??
Please help me out, I'm starting to get concerened about this.

How does it idle? Does the needle bounce all over the place? Does then engine try to cut out at idle when you pump the brake?

If so you may have a vacuum problem and that might be an intake manifold issue.

Is the check engine light on?

it idles smooth havent tried pumping the break will do that and let you guys know. Are these generally dependable SUVs?

Jon- How does the battery look? is it the original sealed AC Delco? Check the battery connections and grounds for good contact. It's possible the battery is getting weak, but the alternator is picking up the slack once the truck is running. Kinda strange tho- these trucks are so dependant on computer/electronics that they usually do all kinds of strange things when the voltage is low: Funky gauge readings & dash lights, tranny wont shift properly, etc..

How about your starter.

In 140K miles on my 96 Trooper I've only had two problems, both times; starter.

Mine dragged slow like that for a week before dumping me flat. Now you know why when speaking of our vehicles, we say SHE.
