This is going to be a long one so sorry in advance!

About 2 years ago the belt would squeak when I started the car but would stop once car started. Then when I would put the air conditioner on the belt would squeak on and off then squeak all the time, then so bad wouldn't use the a/c. Then about 2 months ago it stalled once, started right back up and then didn't stall again for about three weeks. Then car will start but quickly stall but would start right back up. Then it would stall and not start right back up. Have to wait about 15 min to restart. Then it would run for awhile, on hwy doing 55 and it dies. Wait and it starts back up. Went to mechanic a/c compressor all gummed up....replaced that and the belt. Squeaking goes away and jeep runs. Then turned on a/c yesterday and the squeak is back the car stalls, starts back up and then hours later won't start. This morning started up ran for about 2 miles and died. Waited about 10 mins car started back up and ran for the next 22 miles with no problems. Any ideas?

Thanks so much.

 

From Joe Peters and well stated. Sounds harsh but just makes sense:
"Let’s play a game.

You pretend that you are the only one that knows what year/engine/model, etc that you are asking about.

We will all pretend you never asked a question until you provide at least the bare minimum of information about your vehicle".

 

And its a '99 jeep cheroke sport 6 cyl. forgot that important info.

 

Sounds like possibly your CPS is bad.

 

Not disagreeing with cruiser^, Just wanted to mention the new belt may have stretched, settled in a bit. I even saw posted there are two tightening specks, one for new and one for used. My alternator slipping and the voltage being low is normally my first sign my belt is loose. (gets worse with the blower on)
