The original battery died and had my mechanic replace it, ever since, once the car warms up it wants to stall or die when accelerating from either a stop or a slow speed. Sometimes it dies as I pull into the driveway or up to a gas pump or parking spot. It is much worse when the air conditioning is running. The mechanic has "reprogrammed" it several times, no improvement. He also recently replaced a crankshaft sensor? again, no improvement or change.
When it doesn't die, it suddenly kicks in with a jerk like there was a dead spot that I finally got past.
