When i accelerate going up hill the motor losses power (not electrical power) and the check engine light goes on

Your car most likely is suffering from ownerhatesme syndrome. This is most likely caused by:
A)lack of a much needed oil change.
B)lack of a much needed tune up.
C)lack of transmission fluid.
D)lack of a full systems check.
And finally
E)lack of love from the owner. For they are responsible for buying a ford when they know fords are known to break down and go bad over a short period of time.

And if you have done everything said above, the only problem could be a very dirty engine that struggles to get gas into the engine fast enough, or through corroded pipes. A full systems check is all you need to know the steps you need for your (F)ixed (O)r (R)epaired (D)aily to run smoothly again.

Hope it helps.
