You need to check it for soft codes and live data. There is a code being set each time the "Reduced Power" message is flashed.

With the reduce engine performance message on you should have codes stored. But if this issue is only when it has sat overnight then you should also look at the fuel pump for a leak. Remove the rear bench to access the fuel pump cover on the passenger side. If you see fuel on top of the pump, then depending on which State you live in, there could be a 10 year 150K mile warranty on the pump. There was a recall for the fuel pump also. Recall 220 I believe. Run the VIN # here to see if one was issue

If no recall was issue then call Volvo about the fuel pump extended warranty. Good luck to you and let us know what you find.

Checked the top of the fuel pump module and no fuel or wetness was present. One other thing I forgot to mention was; when I was checking the fuel pressure, I noticed the guage needle would swing back and forth quite a bit while cranking the engine over. Is this normal for this car?

It can fluctuate, but it shouldn't swing wildly.
