Check Engine light with mind of its own

My check engine light keeps coming on and going off by itself from just driving from point a to point b. I dont understand why, it drives completely fine, theres no bad fuses or anything. Any Suggestions???

Do you shut it off right away when the light comes on? In order to get the code to stick you gotta drive or run it for a few minutes after it comes on

Next time it turns out, pull over, turn off Jeep. Use key trick (on, off, on, off, on) and the odometer will display the code.
