When I start the jeep and then turn on the headlights the jeep shuts off. If I keep my foot on the gas it will stay running.

What does your volt meter say when you turn the headlights on?

If the voltage drops too low, the engine will stop.

If there is a poor connecton to the electrical system then you will not have enough power to run the jeep.

I assume that the battery is good and so are the cables because you can still start the jeep.

Check the battery voltage with the engine running. it should be around 14 volta.

What's your engine rpm when it dies?
Have your alternator check'd for amp output.
How old is your battery?

Check your grounds. Then check them again.

All thanks for the info the battery is new when the jeep is running the alternator reads 14 volts out. I will have to check the grounds better. the jeep sat for about 6 months.

New batts go bad.
Get a 'battery maintainer' to save your battery.
