This appears to only happen in the wee hours of the morning when it’s fairly cold out. It may just be coincidence but that’s the only time I see it happen. This has happened twice so far in the last couple of weeks, both cold mornings. They resume working normally later on, say after I get off work. The only thing I’ve checked so far are fuses, which look all good, but I’m not sure that would have ever had a problem with only intermittent issues. Any suggestions?
