what\’s wrong with my Bronco?

The last two days my dash voltmeter was reading low but the truck ran fine and then occasionally so would the volt reading. As I drove tonight my truck began to chug. It felt like my truck had no power especially when I gave it gas. I drove for a few miles pulled over noticed it was fine in neutral and reverse but not in park or drive. It soon died and refused to start and a jump start did nothing. when I go to start it it will turn briefly then make a series of clicking noises and do nothing. Any ideas? Alternator? starter? Transmission?
