OK,

I ran the car with new sensor wire, same problem after 7:30 mins. Then I took body off and pushed the wires about, it started, I pushed them some more then it wouldn't start. Then I noticed that the ORANGE wire was rather hot compared to the rest of the wires. I measured the Blue & Yellow and they were both about 32 celcius, then I measured the ORANGE and it was 76 celcius!, but only over the Corally Connector! The rest of the Orange wire wasn't that hot about 5 or 6 c closer to the connector and a couple of degrees hotter than the other two wires. Now the Orange wire also has a gap where it is soldered to the ESC and when taken apart there seem to be heat scorching on the Corally Connectors.

Now could this whole thing be caused by (I assume this is unusual) unusually hot connector?

(1) Why is this connector so hot?
(2) Could this be the answer: Connector gets very hot & thus looses connection?
(3) If I put on a new connector will it just happen again?
