My car starts perfectly but dies when i try to take off or even just after revving it on 2001 Audi A4

My car was running perfectly yesterday and this morning when i turned it on it started fine, it was running fine but when i tried to take off it died. Every time it will start perfectly but if i even rev the car it will die after, i am wondering if anyone knows whats wrong?? thanks

have your fuel pump tested for pressure to make sure its correct and Id start from there
i went down and asked my mechanic might it be that but he said it probably wouldn't be that but it might be the air sensor?
