1999 Ford Ranger Truck Stalled and won't start

Wife driving truck, said felt like it ran out of gas and stalled. She put the clutch in turn key off and on and bumped started it. Said it was chugging and stalled again. Couldn't get it started again. I took the battery to Auto Zone - BAD - replaced w/new. Still won't start. Just one click and not anything else. Tried again to push/bump start and nothing.
Any ideas. Could it be the alternator or starter?
Kind of concerned it is the engine???
She said she heard a noise, not loud but sounded like something hitting under the hood like a loose belt.
Thanks
Scott
