Chk the battery ground cable, Remove and clean. Then chk your charging system at the battery. Should charge between 13.6 and 14.2v If it is charging above 14.2 your alt is barely charging, The further below 13.6 the more amps the alt is putting out. Make sure you battery has adequate water in it. A battery will rejuvinate itself after it has gone dead after sitting awhile,but only enough to last a few minutes. Turning on you headlights would kill it right then.

If you're saying that you already had the troublesome crank sensor replaced then maybe your electrical connections to the sensor is bad, somewhere, along the way to the ecu.
