BMW 528I, lazy starting & hesitation in acceleration

Hi all,
I have BMW 528i MODEL 2000, 90,000 km milage. I face a problem with acceleration during the second operation of the engine. This means that at the first operation during the day, no proplems at all and the car goes in excellent condition, I can drive and speed up as much as want. But when I switch it off for a while (minutes to 2 hours) and try to switch it on again, I face both lazy starting of the engine and hesitation in acceleration. It is not necessarily to face these problems in the 3rd operation. No fault codes given by the computer but I changed the fuel pump, air and fuel filters, timing chain, and checked both the plugs and fuel injectors. Still I have the same problem. Pls any ideas that help. By the way, the last time I checked the computer, it came up with a fault in air mass sensor. I think I have to replace it as the last chance. What do you think?
