also I have noticed power fluctuations from the 12 volt dc power outlet when I have something plugged into it. If that ties into it at all. Trying to list all the symptoms to help diagnose the problem. HELP!!!

First thing I would do is charge the battery and have it tested. Then I would look VERY CLOSELY at all the battery cable and ground connections including connections at the starter. Any corrosion or loose connections can cause weird things to occur. If you find nothing here proceed with other diagnosis.

Thank you for your response. I replaced the battery and checked all grounds and starter connections.Everything there seems to be fine. Still have the U0025 DTC message. I believe that I have found the problem. I had to replace the TPIM. All of the DTC codes have cleared and the functions that were not operating correctly are back to normal. And it starts!
