Dies when warm

Hi I have a 98 Impreza turbo, 2 years ago the engine blew up and was replaced with a Legacy lump.
Everything was fine until recently....

From cold the engine starts and idles perfectly, after 5 minutes idling it coughs, pinks a little, smells of fuel and dies.
It will not restart unless left for an hour or so to cool down.

Once re-started if you raise the revs to anything above idle it will run and run no problem, if a little smokey - almost like over fuelling.

Items replaced -
All coil packs
Crank sensor
cam sensor
Temp transmitter

Tests (which all appeared to be within tollerances)-
Fuel pressure
O2 sensor
Wiring to and from ECU

Im wondering wether it might be something to do with the induction side of things -wastegate control solenoid etc etc.
Any advice would be most greatfully received as its getting a little boring now

Hi, there are no fault codes present.
The fault code system is working as it records when numerous sensors are disconnected.
Im going to replace the O2 sensor next even though the reading are ok.
