2000 Buick century stop accelerating while driving,it did not shut off over heat it did not even smoke, I checked the trans fluid it was ok can anyone narrow down the possible problem

My car has 128000 miles.
My car has an automatic transmission.

The computer may limit engine power if it detects a system problem. You will need to have the computer scanned for codes stored in memory to see what has caused the loss of power and acceleration. You may have a faulty throttle position sensor.
