Got a bit worried, but the only thing I changed from the last time I ran was the firmware ( upgraded to 219 ) so I changed it back to 518 reset the end points and the car ran fine for the rest of the day.

Anyone any ideas?

With the 119 (or 1224), you can easily Over time the motor, and it sounds like this is what you have done. Try upgrading back to the 119 software, and then start very conservative on the timing. We do know that step #54 Boost is 36 deg of timing. (Confirmed here on Rctech).

Brushless motors will not run properly with more then 60deg of timing, they tend to run slow and make alot of heat.
