Your Jeep has what's known as the delayed start, no check engine light problem. The Jeep will not start until the check engine light comes on, on the dashboard. Next time it cranks but will not start, look at the dashboard to see if the check engine light is illuminated. If it's not lit up, then your Jeep does have that problem and your Jeep ecu is in need of repair or replacement. There are components inside the ecu that are going bad and will continue to get worse, eventually leading to a permanent no start condition. There are ecu repair services and replacement ecus on ebay.
