GC freezing mid-sequence

We've been having issues with our 7890B gas chromatograph. We have it connected to a workstation running Windows 7 SP1 and OpenLab/Chemstation version C.01.07 [27]. We have a Gerstel MPS attached as a headspace sampler.

 

We have been trying to run a sequence of 89 samples, and the run has been freezing after a couple of injections (after anywhere from 1 to 5 injections). The software display is identical to when the instrument is waiting for the next injection, but it fails to progress. We've waited up to 12+ hours without a further injection.

I would appreciate guidance on troubleshooting this problem.
