I just got a new BerryGPS-IMUv3 yesterday and installed it on my Raspberry Pi 3 Model B. I ran the tutorial code off github and seem to be getting valid readings from GPS and IMU components. My problem is after about 5-7 minutes of Pi powered up with the BerryGPS board, it hangs and I lose my SSH session. When this happens, the power LED on the Pi stays on and I occasionally see the GPS LED blink green on the BerryGPS board. If I power cycle the Pi, it comes back to life and all is well until a few minutes later and the cycle repeats. I've tried a separate power supply (2.5A) to no avail. If I unplug the BerryGPS board from the Pi, the Pi runs fine for hours on end. I tried piping dmesg output in a while loop to a file hoping I would catch something interesting but so far came up short. Any suggestions on how to troubleshoot this?

This is strange. Have you tried a different USB cable?
Do you have another Raspberry Pi you can test with?
Check the BerryGPS-IMU, do any of the components on the top of it get very, very hot? (E.g. resistors, capacitors,etc..) Some maybe be warm and you should be able to keep a finger top on it.

Thanks for the response. I have tried a different USB cable with another power supply. I do have another RPi3 but it's currently wired up for another project, may take me a day or so to disassemble it to try with the BerryGPS board. Also, I checked the components with my finger and none of them felt hot to me.
I did notice that I may have done a bad job soldering one of the pins on the female header - specifically PIN9 on the Pi. From what I can tell that's GND which is also on PIN6 and that joint seems to be ok so not sure if this has anything to do with my problem. I will try to re-solder the joint later today and report back.

I tried the BerryGPS with another RPI3 and it seems to work better. The first time it died after ~25min whereas before it would consistently die in <10min. After I rebooted the Pi, the second time it ran for nearly an hour. I'll keep playing around with it over the next few days to see how it goes. Very strange.
