engine stalls mutiple times on 1992 Chevrolet G Series Van (G20)

latly the engine has been stalling alot in reverse. ive changed the fuel filter and that didnt do the trick so i pulled the dog house and checked the three eltrical connections to the distirbuter and cleand them with qd eltrical spray and that seemed to solve the problem becouse i test drove it and it ran great well the same night last night i went to go to the store and it started just fine until i turned on the headlights. so i charged the battrey couse i killed it and restarted it and it ran fine so i got it back in its parking spot just in case it dies again and i turnd on the headlights and it tried to die on me again the engine bogged down and almost choked out so i quickly shut off the headlights and the engine came right back to life so iam completly confused on what to do please help me asap it the only car at my house. thank you

It sounds like your Charging System is either weak or your batter is very old. If the battery is more than 4 years old, replace it and then check you van again. If it still dies, then check the output of your charging system. it should be at least 14.1 volts at idle with no loads and at least 13.8 volts with the headlights, wipers and blower motor on full blast. You can buy a volt meter at a parts store for about $15. Measure the voltage at the battery terminals.
