I have a Pi 3 running 0.17 ( installed image on card and then ran all updates)
Pi has a tested good power supply (2.2a), logitech wireless keyboard/mouse dongle attached and an HDMI monitor
I am not using AP mode and instead am connected to the boat's existing wifi using the pi3 integrated wifi. I have another computer on the network running OpenCPN and transmitting all NMEA data over udp.
When the Pi first starts everything is great, the UDP stream is successfully read in and I can connect over VNC. about 10 min later the stream stops coming in and I can no longer connect via vnc however the wifi connection is still good and I am able to use the browser on the pi to view webpages and ping the other machines on network. I have also verified with an additional computer that the udp stream is still being sent at this point, just not seen by pi. The only way to bring everything back at this point is to reboot the pi.
I read several threads about wifi power management and have experimented with turning it on and off with no change in behavior.
Looking forward to any suggestions

Welcome aboard, Will.
So the NMEA data is coming from the other computer?
How have you set up openplotter to get the UDP stream - is that in the nmea0183 tab?
That's basically a front end for a prog called Kplex which does the routing work - does restarting help?
Also, you can highlight the line which sets up the UDP coming in and see if there is any data by pressing diagnostic.
And you can start openplotter in debugging mode as well in the Pi openplotter menu which will show any debug messages if something goes wrong.
