Can anybody help I have mk4 escort efi xr3i IRS had a new starter motor/ ignition coil leads cam belt and new battery/
Run the car for about 20 minuets get nice and warm switch it off and then it will not start sounds just like a flat battery can anybody give me any ideas please

 

Quite a common fault I believe. It's usually heat from the exhaust manifold that causes the starter to overheat. Need a heat shield in there.

 

As above. Heat shield or wrapping the downpipe cured it on mine.
