Could be a weak battery and/or alternator. You say the battery is "fine" but have you actually had it load-tested? If you have a voltmeter (not the one in your car, a handheld one such as a multitester), connect it directly to the battery terminals. With the car not running and…

Thanks m8 will take it to a local outfit.
AutoZone will do a voltage charging test for you free.
