I was driving home from work tonite or stuck in traffic to be truthful when my Z cut out. I would not start it again but all seamed to be ok. Pushed it to the side of the road and waited for recovery. When he arrived it started first time ran for 5 min then stopped again. 10 min later same again????

Seems to be heat related? Got it going again and drove 7 miles home sat out side my house for 15 min all fine. I know Z's suffer from dodgy plugs under the bonnet but anyone know were to start looking?

sounds like ptu to me

Yep, sounds like PTU failure.
