Hi,

I turned my car off last night for about two minutes. It wouldn't start just a moment later. When I turned the key there was just a clicking, but nothing else. It took a jump, and I left it running for a few when I returned home. It died while sitting, running in my driveway.

I just replaced the battery two months ago when I having a similar problem (though the key would take a jump and continue running).

This leads me to believe that it's not the battery. Does it sound like it could be the alternator?

Yes sounds like the alternator.

GENERATOR NO-LOAD TEST
Connect a voltmeter positive lead to terminal B+ on generator and negative lead to ground. Start and run engine at 2000 RPM, with all accessories off. Read voltmeter when voltage stabilizes. Voltage should be 13-15 volts.
