Why does your 1992 Buick lesabre seem like it is running out of gas to the point it dies but then crank up after turning the key switch on and off a few times?
A 1992 Buick Le Sabre could be acting this way due to a faulty fuel pump.
I had this problem with my 1994 Buick LeSabre and it no longer happened when I installed a new battery. It's been at least 6 months now with no recurrence of the problem. Before the new battery, I noticed that if I waited about 5 minutes after turning off the car, I could get the lights to turn off. Seemed like something had to cool down.
