Di2 cutting in and out

So my ultegra Di2 started to act up today...

It's been working perfectly ever since moving everything over to a new frame last month, but 15 minutes into my ride today, it just stopped shifting. A few minutes later it would work for a moment. Then stopped again...so on and so forth. I just went through the whole system, disconnected and reconnected every wire, but that didn't solve anything. I also noticed that it would randomly go into micro-adjust mode when it is working.

Battery is/was sufficiently charged, and the bike has not been washed/exposed to any harsh weather/conditions recently. The entire system is about six months old and this is the first time that I've experienced an issue. Unfortunately, I only have Mac/iOS (do not have wireless unit installed) at home so I'm not able to connect to the E-Tube software to run diagnostics or update firmware.

Has any one else experienced something similar? Or have any ideas about a solution?
