i drive a megane coupe 2.0 sport

my car starts first turn of the key when its cold but when it heats up it looses all power when movin the only reason i get power back is cause my car is still movin and there is no warning lights comming on telling me whats wrong. the car will stole at traffic light, struggle to start again when stoled,

CHANGED

* idle control valve
* faul filter

PROBLEMS ELIMINATED

* cold start sensor
* map sensor
* map pipe
* ignition coil/plugs/leads
* Top Dead Centre
* gaskit
* overheating
* changed fuel filter

im now going to try and eliminate

* kat exhaust
* lanbda sensor ( dont no if this will be eliminated cause the emissions test was perfect )
* all fuses

im now thinking that it might be a relay box but cant find out till monday 28th may

Welcome to the forums. I have moved your thread to the engines forum to give it a wider audience.

I have also renamed it to assist future search queries and give members a better idea of what the problem is.

You could try a forum search for "loss of power" as this has come up before.
