Electrical prob

The last month or so my charge light would come on from time to time but it would go out in a few seconds, I checked the battery and it was fine, this went on for a while until the last couple days the charge light has stayed on the car was still running fine. Now this morning the charge light was once again on, but was joined by the brake light, the abs light and the traction control light, as well the car started to stall I noticed the radio seemed staticky and would fade in and out, then the car did stall it restarted after a few tries ( the battery still had life) and I was able to drive it home a few blocks away. Before I go spend big money fixing this does anyone have any idea as to what may cause this...
Thanks for any help.
