Why does my grand Prix keep shutting off?

(1999 Pontiac Grand Prix)

If I change the maf sensor and delete the code from the computer it will run again but eventually stall, the motor is a 99 and the car is a 2002, could the computer be bad?

It always puts the mass air flow code into the computer and the other day we didn't change the sensor when it shut off and we just erased the code and it started just fine. The motor has been in the car and ran great for the last few years. Could there be another sensor putting that code into the computer and keeping it from running?
