Impossible to solve.

Give us age, miles, model, spec etc and some history...

If you want us to solve a problem that a garage with the physical car cannot, you must give us the fullest infoirmation possible.

You have given us nothing..

The fan can run continuously when the engine is running hot. It can also happen if the thermostatic switch fails, so may be nowt to do with an engine problem. As madf says, more info needed. what is the temperature gauge doing before power loss? You may have airlocked cooling system,so bad circulation, worn water pump, head gasket failed?Is fan on with ignition and a cold engine? Engine oil and ATF oil ok?
