Unfortunately, you've run into the problem with trying to run two sensorless brushless motors from one ESC. Sometimes it works, most of the time it doesn't. The problem is that the ESC depends on pulses received back from the motor to determine when to send the next pulse. With two motors, it's receiving mixed signals.

The only reliable solution is two ESCs for two motors.
