I thought about the battery. Same result with fully charged battery.
Also, same program, with same commands worked the day before.
I have tried all combinations to try and determine issue.
i.e. Hover with 100% power. Still shuts off in between commands.
Behavior is like program command steps execution is slow to load next step and during the step load/setup process the motor is shut off.

I am returning the drone. Have already put in enough time troubleshooting a brand new piece of equipment. Worked beautifully out of the box. Next day worked for about 1st hour then issues. First major drifting, then propeller shutdown in between program commands.

I am open to another try of your product once you resolve your quality/reliability issues.

In between program step the propeller stop and start:
Example of behavior:

1. Take Off
   Propellers start drone lift off.
2. Hover 5 seconds.
   Drone hovers propeller all OK.
3. Move forward 1 second.
   All propellers shut down for 1 second.
   All propellers start up and drone scoot forward across the floor for 1 second.
4. Land
   All propellers shut down for 1 second.
   Propeller turn all then turn off.
