Default Viper VTX10r problem initializing

I bought a short course truck second hand that had a VTX10r in it with a 17.5 motor and decided to run it in mod with a Viper 10.5 and it ran great for quals and during the main after about 7 minutes I suddenly lost all power but still had steering so I assumed I might not have charged the battery and brought it back to the pits put a new battery in and the esc won't initialize. I temped the motor after my run and it was 135 which was consistent with the temps I was running and the esc was cool to the touch, I inspected the sensor wire and it was fully seated and I even tried a new wire but still when I push power the esc turns on with only the red power light on and I can't enter program mode. Is it possible the esc died or am I missing something? The previous owner said the esc was only about 6-7 months old and he only ran it with a 17.5 in blinky mode and the esc limit is 2.5 so there's no way a 10.5 should have over amped it especially with motor temps of only 135-140, any suggestions would be appreciated.
