Hi My 1.6 LX CMax runs perfect from 1st turn of the key untill you stop say garage then try to start when she’s warm and it just turns over but if you leave say for 10 minutes or so and you come back it starts on the button but it a bit embarrassing when you sitting there for 10 minutes like an onion

I am assuming it is the petrol 1.6 here.

I had a car that did just that. Cold start ok, hot start (within a few seconds, like a stall), was ok, but at a filling station or similar short stop, if turned off I had to wait 15 to 30 minutes. That turned out to be a burnt out valve (low compression).

But there are quite a few other temperature sensitive bits: Coil packs, Fuel vapour locks, Throttle valve ...

I would test for good spark when warm, and then get a compression test done.

To safely test for spark, get an old plug, increase the gap to about double normal gap, wire the metal body firmly to a good earth on the engine. Move one plug lead to the test plug, crank, watch & listen for spark, & repeat for each plug lead. (Never crank or run the engine with a disconnected plug lead.)
