Serial data randomly stops

[canyondellomo]

Hi there,

I have a MPU-9150 set up with a Sparkfun 3.3v Pro Micro. When running this code, serial data transmission will randomly terminate, anywhere from 6 seconds in to over a minute in. It never lasts for more than around 70 seconds.

How would I fix this issue? I tried adding a Serial.flush() to hopefully clear up the serial port but it still seems like its getting clogged up. My only hesitation was that you mentioned it would run on the Pro Micro, so I wanted to ask here for clarification.

Thanks so much,

Canyon
