Try shorten wires, add capacitors to I2C lines. Shorten wires to motors. If this not help, add noise supressors on cables.

RE: Problem with the I2C port
What is the problem? I don't know. Simply, suddenly the program doesn't work.
If I activate the debug, the last message on the console is "Initializing IC2 device..." .

I tested MPU device in a UNO board and works fine. The same sketch in LEONARDO doesn't work.
