Alternator, wore out accessory drive belt, bad connection, dirty connection at the alternator or batteries. Check those things. Also take a volt meter and see what the output is on the alternator, if it is below 12.5 volts replace it. If it is below 13 volts then it is getting weak and you should think about replacing it. The standard out put of an alternator is 14 volts on average with an average of 100amps.
If you replace the alternator get one with life time warranty, that way if it goes out again you just take it off. Take it back to the parts store you got it from and get a new one. I like shopping at nationwide parts stores for these kind of parts that way if you are traveling and the alternator goes out you most likely will find that brand parts store near by.
