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.
