Honda EU200i issue

I've had an intermittent problem with my Honda EU200i. It's happened since new but couldn't reproduce the problem. Finally, this fall we were camping in the mountains of Idaho. When the temperature dropped below 45 degrees outside during the evening, I had troubles getting the generator started in the morning. I would go through the normal startup procedure but it would only run for about 5 - 10 seconds then the Oil Alert Indicator would come on and it would shut off. I would repeat the process 2 or 3 times until it would start and run normal. Oil level is normal. My question is whether others have experienced a similar behavior and what to do to resolve the issue? It's time to change the oil this fall and was wondering if a different blend of oil may resolve the issue? Thanks in advance.

Jeff.
