Phd2 keeps dropping star

The guide star may be too dim. Light pollution issues, clouds ...etc. Post your log files.

Focus? Tried raising the gain? Tried 2X binning?

Post your PHD2 GuideLog, from the PHD2 folder, check that the date in the filename is relevant
We have no idea what equipment you have, so if we're into guessing:
1) Using Star Mass detection ? Try Min HFD instead, set to 2 pixels.
2) The exposure may be too fast, 2 to 3 secs is common.
3) Uncorrected Dec Backlash
4) Poor Star Profile.
