You could get a "Global scan" done,
This scans all the modules,
of which the instrument cluster is one of many,
And they all depend on interconnectivity for correct function.
If the speedo chip or connection at the back is faulty it "could" give rise to running/starting faults.
The scan will tell if there are any faults in the modules.
