Is it an Alarm problem?

I have a 97 Grnd Chrkee, every once in a while the vehicle will not start. I have checked the battery, and the starter. When I pop the hood I hear some clicking from the relay box. If I let the vehicle sit for 8-10 hours the vehicle will then start right up?

No, you gotta have something wrong with the starter, ignition switch, or power/ground.

What do u mean powr/grnd? Do u mean the wiring? I now know it's not the starter. I just replaced that, and I still have the same problem. ign switch, what can I do for that?

The main cables on the battery is what I am talking about. For the ignition, you'll have to test them under the dash when you turn on the car.
