Acceleration failure while in motion

My acceleration fails while in motion especially when I drive over bumps, potholes or when the general temperature is high but the car temperature is normal. I have replaced complete pedal sensor, nozzles, relays, complete fuel pump and housing, crankshaft sensor and top sensor, injector mount yet the problem persists, whenever it happens if I restart the car, it will accelerate and then stops after some time or a day or two. Thanks
