Reduction in power?

Lately I felt that the car has lost power in 2nd gear and just doesn't have the head getting pulled back feeling when you give it some stick. Before I take it back to get it looked at do you think this could be related to increase in temprature therefore loss of power?
If I was to guess I would say I feel like I have lost 20~30% in power (in my mind).
