1999 Chevrolet Camaro V6

1999 Camaro V6 edition with 155,000 miles. Past month or so I have had all sorts of weird things going on. The main problem is my car kept dieing and would need a jump quite often. I figured I would check the water cells in the battery which I did and they were empty so I simply filled them up. Started up fine and went about then my car wouldn't start again and needed a jump once again this time it was by a portable car charger / jumper from autozone and since then my car starts everytime. However just recently my car was just idling for under 30 seconds when it started to get a little shaky and the lights in the car were dimming in and out and what not so I just turned it off. It felt like something was about to die. Which by the way everytime I get jumped I have to reset the time and all that stuff. Also another small problem I am concerned about is sometimes when I accelerate quite quickly my car seems to hold back or feels very sluggish and or like just studder a little bit. It's like its not full on. Any help is appreciated.
