1999 Buick Regal 6 cyl Front Wheel Drive Automatic 200k+ miles

99 buick regal 3.8 supercharged high milage. Car would die while driving, after several attemps would start and run for a while then stall agian. Got it home it will not even crank now and when I hook up my scanner to the obd port I get power but it fails to connect to the computer. Could this be caused by the pass key system? Just a guess. I really need help.
thanks

Make sure the battery fully charged
with key in and in on position
what do you have for light s
do you have a security light on or blinking
and if so suspect the pass system
also do you have check engine light on
you should if not check fuses
