2003 Sonata stalled while driving
 

I have a 2003 Sonata v6 that stalled while driving,( i filled it up earlier today) it has not started right away after the last 2 fill ups and I've replace the purge valve twice already. this time the check enginge light is not on so i cannot get a code. I have checked everything i can think of. Any suggestions?

My guess would be the mass air flow sensor.
