maybe, just maybe... you have a sulfated battery or alternator cable. My first used car had that problem; an alternator cable was not sending enough current to the spark plugs because the copper inside had sulfated and was rotted.The battery light keeps coming on and sometimes everything is fine and sometimes the car dies and take awhile to jump. The times I've taken it in recently. All the testing says everything is working like it should be. The guy thinks there may be a short or wires going bad and they don't do that type of work in their shop.
As it is inside the plastic of the cable it is not visible until they begin to measure the currents.
