Other than voltage and the number of satellites, there isn’t much else preventing the module from working. You might be at location that has poor satellite coverage. I’m assuming that the GPS module is located on the top of your fairing. Look at your data in Race Studio. Compare working and non-working sessions. Six satellites is a weak signal. Look for the number of satellites going to zero intermittently which should indicate a broken cable or connector.
Ask your competitors if they have the same issue.
