Car keeps cutting out??

[Lonsdale]

I have just recently built a b44.1 after first 10 mins of runing it in it keep cutting out , when you give some throttle it just stutters in power, i check the motor wires etc, then after bout 30 second rest it is fine? I dont know if its the esc over heating? Im running associated xp 450 esc with reedy 4900 kv brushless , orion carbon 6000 45c 2s lipo and a etronix pulse radio on factory setting , any help would be very gratefull cheers

Im running the grey etronix receiver, ive heard they had problems with these rx's would this be the cause?
