Does the battery light come on before the engine dies, or after ?
After is normal because the engine is not turning the alternator.
Is the check engine light on when the engine is running ?
Common causes for stalling are a dirty throttle body or faulty idle air control valve.

My 2002 Aztec radio locked, trac on light, abs, service engine soon light, securiity light and others on, is there a way to unlock the radio and can I replace the BCM and ECM myself? The dealer says over 1100 bucks for just that!

try disconnecting the cluster fuse and the radio fuse and see what happen if everything work...u might have an open circuit or a short on one of the electronic in your truck

Your problem is either the Alternator isent charging its 13.5 volts and the battery is flat or wont hold the charge SO do this.
Jump start engine again let it run for 2 minutes then turn on lights,, the head lights should go bright at 13.5 volts. it engine cuts out..and the lights dont go bright,, then the Alternator is not charging,,,, If they go bright and still cuts out the batterys NO GOOD.
Replace battery or get it checked outit must hold 12volts all the time Let me know how you get on.

prob in lock mode because they had the battery disconnected take it back make them re-program radio

Same thing happened to me.
You will have to take it to the shop and have a dealer fix it.
It is what they call the "cluster" up by the firewall behind the engine that controls all the functions of the car.

The high beam light flashing means you have a high beam burnt out. It flashes when you put it in gear because your high beams actually double as your daytime running lights, only on a lower power.

the starter switch could be bad when it wears out you the same kind of problems when it happends try to wiggle the key ( with out turning it off ) if it comes back on that is the problem
