hesitation on acceleration

anybody got an idea on what's going on?


i drive the car normally and all it OK.

i hold the gears (manually shift) and it's not so problematic in first but in secopnd gear at high rpm, it starts to hesitate and like there is no gas... i let go and floor it again and it goes ok for a second or two and the hesitation comes back.

fuel pump? or filter?
