99% of Turbo riders have never experienced a power loss such as you describe. Overheating seems unlikely - I sometimes ride up a 700 ft. hill using the throttle mode, and the motor gets warm, but not hot. The one part implicated in the rare issues like this is the thumb-controller, which was delicate on some bikes, and would get flaky and drop into regen mode (flashing icon) when climbing.
The cure on mine was the dealer replacing the controller. Hasn't happened since.
Based on your description, I'm wondering if there is something the shop is doing wrong during setup, as they don't sound like they knew the bikes very well..
