hi,,can anyone shed any light on whats going on with my car? basically it runs fine when cold,but when normal running temp is reached it cuts out and the coil light flashes.

i then have to wait about ten mins before it will start again,but i can only drive about two miles and it cuts out again??

i've been told that it could be the fly by wire?? but its got worse over the last few days and sometimes happens when the engine is cold(but mainly when its at normal temp).

i'm at my wits end and would grately appriecate any information and roughly how much it would cost to fix the problem.
