My 5D Mark II is set in Manual Mode with an attached Speedlite (580EX II). I've set the manual settings to 1/400-F8 for an outdoor portrait. When I depress the shutter release the settings switch to 1/200-F8 and record the image. Overexposed.
If I fire off 6-8 images, the camera will record 4 or 5 images at 1/200-F8, then it will record 2-4 images at 1/400-F8.
I have already examined every menu function and tried (unsuccessfully) to reset the camera's settings.
Does anyone have any explanation that could help me solve this issue.

I didn't know that the camera will reduce shutter speed to MSS when in Manual mode. Interesting.
As Tim said, you're past your max sync speed without HSS enabled. You eventually exceeded the Speedlites power buffer, so while it's recycling it didn't fire, hence the camera went back to shooting at 1/400.

On my 5D III and II it bumps it down to 1/200th if I power up a flash that doesn't have HSS enabled (I tested to see if it made a difference whether the flash was in manual vs. E-TTL mode, but it made no difference.)
