Need help! car bogs at stand stills and jerks when it shifts gear

What is your question?

So my dad bought this Chevy colbat 3 years ago from a dealer used I would say it had about 17k miles on it, problem started last year. We do its tune ups on time but out of the blue the car just started to act weird the car would bog and or turn off at stops, the engine will start to jerk when it would change gears and when we would drive the car the all the dashboard lights would go off and the gauge needles will start jumping around that's when the problems begin Any help would be appritiated thank you!
