Help with electrics

[rondoolaa]

A mate of mine has a problem,

His on road car was on the track and it was like it kept losing power, it would slow down and servo wouldn't work then either it would start again or if car was shook it started again but then the same fault occurred, he purchased and changed the esc, receiver and power cap attached to esc and the sensor wire and it still has the same problem

Has anyone any idea as what could be causing the power / signal to drop like this?

What lipo's are being used? Is the C rating high enough on them and are they new or old?
Voltage might be dipping to low
