99 Cherokee won't stay started
 

My 99 Cherokee will crank up everytime and even make it around the block once. But after about a minute it starts to putter and quit on me. It will crank right back up and repeat. I have replaced the distributor, the spark plugs and wires, and the alternator. Any other low cost home maintenance things i can do to fix it before i fork out cash to a dealership.

Check the CPS and the wiring to the CPS
