Why arduino serial moniter stops displaying mpu6050 output after some time?

I used the following code.after few seconds mpu stops sending data and when the serial moniter is aborted and clicked again than it starts but it again stops after some time.Since mpu stops sending data the processacing gets continued over the last value,and the motor stucks according to last value.Community,please help me.Or provide me a base code to work on. The code I made use of:-

#include <Wire.h>
#include <AFMotor.h>

AF_DCMotor motor(2, MOTOR12_64KHZ);

int flag = 0;

long accelX, accelY, accelZ;
float gForceX, gForceY, gForceZ;

long gyroX, gyroY, gyroZ;
float rotX, rotY, rotZ;

void setup() {
    Serial.begin(9600);
    Wire.begin();
    setupMPU();

    motor.setSpeed(200);

    Serial.println("Its ready!");
}

void loop() {
    recordAccelRegisters();
    recordGyroRegisters();
    if (gForceX > 0.35)
    {
    motor.run(FORWARD);
    }
    else if (gForceX < 0.35 && gForceX > -0.35)
    {
    motor.run(RELEASE);
    }
    else if (gForceX < -0.35)
    {
    motor.run(BACKWARD);
    }
    Serial.print(gForceX); Serial.print("\t\t\t\t"); Serial.println(gyroX);
    delay(100);
}
