Orion 100amp cutting out???

[rc_penguin]

Right i have decided to run the spare car tonight (X5) as mine is in a bit of need for a rebuild and im awaiting a screw kit from nor-tech before i do that ,

Anyway the spare car has an orion brushless esc in (100amp one) but after about 6 mins of running it cuts out randomly , the esc is stone cold so dont think its thermaling and lipo's still reading a 7.92v so no chance of lipo cut-off kicking in either. Its also only running a 13.5 so not running anywhere near the limit.

I know races are only 5 mins but dont want to chance it cutting out during a race and if it can be solved brill

Thanks in advance,
Will
