1993 Pontiac Grand Am 6 cyl Automatic 198000 miles

I have a pontiac grand am, and the other day I tried to start it, nothing happend. Went out yesterday and it started up just fine. Drove it all day, went out there today and drove it to the store, but as I was turning into parking lot the car just shut down, and would not start back up. Its trying to start but wont turn over. Thought maybe the alternator is going bad, but not to sure.

Cranks but no start condition-do below to determine whether it's fuel or spark issue:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.
