I have a 97 SC2, when trying to run the car, the lights start to go dim as if the alternator doesn't work. But before that, my battery light stays on, then the airbag light comes one, then my dashboard needles die. And other sensor lights do weird things. Then the engine tries to stall. Is this just an alternator issue or do I have a bigger problem at hand. Also should note that the battery is new from 4 months ago.
If you have already checked the obvious, I would have your computer checked for codes, it could be on it's way out.
Sounds like either the alternator, battery (yes, a 4-month old battery can still go bad), battery connections are dirty, cables are bad, or the computer. You'll need a good voltmeter to determine the battery condition. Measure voltage at the terminals before starting (should be 12.5V) and again after the engine is running at idle (s/b ~14-14.5V).
If the voltage is not above 12V, then it can cause strange behavior.

I had the same thing happen on my SC2, 1997. Replace your alternator before you end up like me - running on a battery in the rain 5 miles home.
