When driving uphill slowly my mastery warning light blinks then I lose power to accelerate if I press all the way down it moves off and the light comes off. But if I stop the light stop blinks then I regain all the power to leave off smoothly and more powerful than pressing all the way down. Can I please get help?

Yep, this happens when the car goes into limp mode. Usually, the problem will be the accelerator pedal position sensor or the throttle body, we should run the codes which will have a code to point us in the right direction.

Here is how to change out the accelerator pedal position sensor in case a code is stored if it. Check out the images (below). Please let us know what happens.
