Hello and welcome to JustAnswer!

It sounds as if you're losing throttle response. If you're losing control of the throttle then odds are an electronic throttle control system fault code is setting and the engine is going into ETC limp in for safety. There are many possible causes for ETC limp in including the accelerator pedal position sensor, the throttle body, wiring, the powertrain control module, a vacuum leak, intake restriction or incorrect MAP sensor signal.

What warning lights are you seeing?
