Hmmmm ... dying on you probably isn't the thermostat temp sensor - doesn't sound quite the same. What about the TPS? Did you adjust it when doing the head??? I'd fiddle with it a bit first ...

The temp sensor going would make it run rough on petrol hot or cold (less noticeable on gas), but worse when hot as it stills thinks its cold and throws fuel into it and idles up ...

I'd try TPS position and back off the AAC screw first (so its idles high) and tweak from there ... if that fails, maybe a small investment into a new temp sensor??

Good luck mate!!
