my car started to act weird yesterday, sometimes when i put the car in the ignition the battery seems to discharge or something, all the lights go out and no radio or anything. then i can't turn on the engine, but if i leave it on the on position and wait about 3 mins it looks like the battery wakes up or something and the engine starts right up? It doesn't always happen but i don't wanna get stock anywhere. would it be that the battery is gone bad or is there another posibility?

 

I would check the connections at the battery for corrosion, and also the ground strap from the block to frame. If it still acts up, check the connections at the starter.
