What fuse or power circuit only gives power when the engine is acutally running?

For a project I'm doing I need power from the car but only when the engine is actually running. So I dont mean power upon contact (loads of circuits to choose from), but a wire that only gets live when the engine runs.
I need about 5amp tops.
Its for a 3.0i.
Is there such a circuit present wherefrom I can draw power?
I know the eps only starts working when the engine runs but the eps fuse is live on contact. It probably (I guess) gets data from the ecu over a data bus as it's a pretty complicated system
