P0A94-127 code on my 2007 Camry Hybrid is what ?

Question

After driving on I95 @70mph it just 'kicked' car jerked forward and engine power was not there anymore. I used my right foot to add more acceleration and no response from the engine...it was slowing down. And the code 'check VSC' and 'check hybrid system' went on as well on my dash . I pulled over and and turned my engine off and after 1-2 min I pushed the button and it started again and for 60miles of my trip no issue. On the way back home same thing happened and I did the same again, pulled over & restarted agin after 1-2 min and no issue all the way home. Why ? What is going on ?
