Check your maf sensor. If its dirty or not working right I can send bad info to the computer. Try cleaning it with maf cleaner. Walmart, Pep Boys has it. I had this problem especially when gunning it. I Cleaned it and it ran better but ended up buying a new maf and it ran great.

If you have a K&N filter be careful of over-oiling related to the dirty MAF AGB1976 mentioned. As far as plug wires go, so far for the best bang for your buck with no issues that ive found is GMPP plug wires, they are red and black They are decently priced and fit very well. Spark plugs as well need to be checked.

If your interior lights dim does your headlights also dim if they do then a battery and or alternator is your problem

Sounds you have a battery issue. Especially i=f this just started suddenly out of nowhere. Drive the car to an auto parts store and have then check both the battery and the alternator.

I would have them test the battery by itself too. Diconnect neg and pos cables and check it that way.
