Sequences Close Prematurely

I connected SGP to my SBIG 11002 and selected the internal chip. I connected the camera and filter wheel in SGP. I set up a run sequence for 6 exposures. I selected the file into which to deposit picture files.
I selected PHD2 as the autoguider from the SGP control panel. I opened PHD2 and selected the SGP API Autoguider as the PHD2 camera. Looping in PHD2 worked fine.

One selecting run sequence I got an SGP message after about 10 seconds saying my run had completed.
