any luck with this one? sounds possibly like a faulty temp sensor?

Are you turning the key immediately to the start position (3) or are you letting the key pause at position 2 (ignition) for 1-2 seconds before firing? If you give the fuel a chance to pressurise (especially when cold) you'll give the engine a better start and it shouldn't kick out. Failing that, the component at fault could be....

Fuel filter

Fuel pump

Spark plugs

Idle Speed Control Valve

There are other probable causes but I would start with the fuel filter, it's the quickest and cheapest one to eliminate. Then spark plugs, then ISCV.
