Based upon your information it sounds like a thermal issue, related to something heating up in ten minutes that causes a sensor measurement to read out of bounds and trigger the turtle. Then when the car is OFF and cools down the reading is back in operating range.
Since it restarts after cooling then nothing is "broken" as much as it is temporarily out of specification. It could be an electrical component such as a ceramic capacitor, or the sensor, or it could be an actual thermal heating event.
If you have one of the phone apps to monitor the cell temperatures to see what happens over the first 10-15 minutes looking for clues.
After a series of tests I found the following problems
1)the turtle turns on only after the arrow goes beyond the border of the eco mode
if you release the gas and the arrow is again in the eco range, then the turtle disappears
2)Lexia shows good cell voltage throughout the ride
15mv with a charged battery
30-35mv with discharged battery (20-30%)
3)There is a difference in the temperature of the modules
