Random cut outs ... Ideas needed !

[szymanski2oo1]

Hi all, need some ideas..

I ran my desc410 today with a skyrc toro 150amp esc and trinity monster power 5.5 sensored motor ... Randomly on occasion if I crashed and stopped still the truck would not move ... Steering was fine ... And when pushing throttle back and forth it looked a bit like it was rocking like it was trying to do something... To get it going all it took was a nudge forward from another truck and it was back to normal ... It didn't happen every time I stopped still ... Just randomly ... The Esc is new ( 4 meetings old) and motor is second hand ( looks tidy but don't really know how much use its had) ...
I'm going to try change sensor lead , motor wires are soldered well , just wondered if anyone knows if this is a problem indicative of a particular issue ?
Cheers
Jon
