stalling

89 wrangler misses and then stalls when headlights are on and i hit the brakes.it runs good untill lights are on.engine rpm drop and it stalls. sounds like bad miss,or fuel problem.please help.

It sounds like maybe the alternator is weak and with the added strain of llights the electronic ignition may not be getting enough voltage to function properly. Most auto parts stores can test your alternator. You might also want to check for any electrical shorts or corroded connectors / damaged harness.
