In SGP, my sequence finishes Light Frames and pauses to allow me to slew to zenith to place a flat panel in place.  PHD2 complains that the guiding is lost.  I can manually stop the guiding, but when I unpaused SGP to start the flat frames, the mount starts to slew back to the target.  In PHD2, I did have the box check for “stop guiding when mount slews”.
Sorry, I don't have my logs with me to share.

Any Ideas?

With no information, we can't really help you.  This sounds like more of an issue with SGP and your scripts, so perhaps you should post your question on one of their forums.

PHD doesn't slew the mount (unless you manually do this for the calibration assistant), so this sounds like something in SGP

Can't say much more than that without logs

PHD2 always generates logs.  If you have access to PHD2, then you have access to share your logs using the built-in log uploader under the Help tab.

I did tried SGP forum, but no replies.  I'm traveling right not and don't have my imaging computer.  I will followup after I return home.

Let me expand on my initial response and perhaps save you some time.  When doing automated imaging, the session manager app (e.g. SGP) is always in control and PHD2 only does what it is told - no more, no less.  PHD2 doesn't know anything at all about what is going on with your imaging session - focusing, centering, slewing to a new target, plate-solving, etc.  The session manager tells it to start or stop guiding and that's about it other than start-up and shut-down actions.  So if you think PHD2 is guiding when it shouldn't be or vice-versa, that is going to be a problem with how you've configured your session parameters.  The session manager apps like SGP and NINA produce text log files that record what they are doing with each log entry time-stamped.  So you need to figure out what time you had the problem, then find the session manager log and see what it was doing at that time.  If you wanted guiding to be disabled, look to see if the session manager told it to stop.  The logs are human-readable and you should be able to figure out what's going on without being a programmer.  This is an important skill to have if you're trying to do automated, unattended imaging.  Things will go wrong at times, that's just the norm.
