If it was an immo problem then it should do it hot or cold. You really need to take it to someone who knows what they are doing like an auto electrician. I presume they have tried things that can be heat affected like cam/crank sensors? One fault I have had on those engines is a sticking EGR valve, if it sticks open the lift sensor cuts the fueling. Try running it with it disconnected. Let me have the symptoms & i'll try and help.

I agree - its not an immboliser fault as this would cause the issues all the time

Common things that cause failures to start when hot

- Dying Crank sensor
- Engine temperature sensor mis-reading, giving an incorrect fuel/air mixture
- Air intake temp sensor - i would have though it'd still start, unless its sayings 1000degree's outside

Def not an immo issue , I would take it to someone with a better knowledge of diagnostics ie not just looking at what the codes say or don't say then playing parts darts with your hard earned it needs a right good scoping :)
