Unhappy Mercedes 280SEL misfires when hot.

Mercedes Benz 280SEL - runs perfectly when cold, has an inline pump, fuel injected petrol. But misfires and has a lack of power when hot. I think its something to do with the fuel.
Any advice would be appreciated. I have already cleaned the fuel tank, and put in a new fuel filter, plus all spark plugs, leads are new & points (and the valve clearance has been adjusted.)
P.S - When it misfires, it feels like there is fuel starvation.

An open circuit in Temperature Sensor II or the wiring leading to it.

Any chance you could include a picture of where Temp sensor II is? Or a brief description?

Thank you,

Go Packers!
