after driving it for fifteen minutes it turns back on
Disconnect battery cables from battery for 30 minutes and then reconnect battery it then resets.
To be completely ready it takes about 30-45 minutes of driving for the computer to complete all tests and to allow smog testing.
45 minutes is perfectly acceptable but you may prefer 45.0 minutes
The average Jeep computer takes about 20-30 minutes of driving to perform all the required tests.

30 minutes
sounds like an ignition coil
MapQuest estimates the driving time as 3 hours and 28 minutes.

No. Just reconnect the battery and let the car idle for 5-10 minutes and then start driving the car. The car will relearn your driving habits after a week or two. . . .
