Vehicle cuts out whilst driving.

When key is turned to restart vehicle, starter motor fails to operate. If vehicle is left around 5-15 mins, it will restart and drive without any problem.

I have tried to recreate problem both in workshop and on the road but unsuccessfully.

Codes stored are:

P1525 adjustable camshaft solonoid control (Y49).
P1235 recirculation flap signal output.
P1236 aircon compressor clutch output stage.

Any ideas appreciated.

Cheers, Ian
