Problem resolved. The problem was the configuration of the INT pin. MPU6050 for some reason does not respond when it issues a pulse with a duration of 50 us, when DMP data ready. The problem was solved by the INT pin configuration so that the MPU6050 held its pin until the data was read.

I have problem with MPU6050. Approximately every 1 - 2 minutes I get the NACK on the I2C bus from the sensor. This situation arises entirely by chance. I receive NACK during read "Current FIFO buffer size" register, but after reading this register again, the device responds normally. Do not know what could be the reason?
