Keep having the message, engine power reduced and traction control off pop up almost at the same time. And when this happens the car has almost no power and have to put the pedal to the floor for it to accelerate. And at times it seems like it is getting power back but goes right back out. Please help!

Have a mechanic scan for codes you may have a two fold problem here especially because brake pedal is going to floor. Make sure to check to see if any brake fluid in reservoir. Sounds like an ABS problem.

Normally traction control is associated with an ABS problem either a sensor or what ever is wrong with it. If you have codes what are they we need to know to lead you in the correct direction. The reduced engine power can be anything form a throttle body problem or accelerator problem or even a weak battery. So if you have the codes please send them.

480 is a short to ground or a voltage problem with the cooling fan circuit could be low voltage or a wire bad, or bad motor. The c242 is tcs is off and is a serial data problem so a pro will have to look at that to fix it, it may be one module isn't talking to the other one. The last two 2127/38 deal with gas pedal which may be a bad gas pedal sensor because it isn't giving a good reading to throttle body that is why you have low engine power. There is no cable any more it's electrically controlled from pedal to throttle. But a mechanic is going to have to look at it for the traction control. It can be a short or the module problem.

I just recently had a new pedal put in, is that something that has to be programmed or is plug and go?

I tmay have to be programmed but if it was professionally done they did that. If you are still getting the code take it back to where it was installed and let them figure it out as it still shows a problem and wasn't fixed. It can also be a shorted wires as well.
