Stalling can occur for several reasons. The first step in troubleshooting these cars is to check the fault codes.

It sounds like your alternator is no longer recharging your battery. You probably need a new alternator.
There is most likely something in the gas tank. When the car starts the fuel pump starts sucking in fuel and when the trash gets to it the gas will not be able to flow through the clogged pump so the car stalls. When it stalls the fuel pump stops suction and the trash comes out allowing it to start again.
