I run it for a few minutes, and then the NavX dies and the yaw reading stops updating. Occasionally, it starts working again after some seconds, but other times it requires a reboot to work.

Here's what I checked.
- I'm using the latest version of the library.
- NavX has been fastened down to the RoboRIO and ensured a secure MXP connection
- NavX is plugged in to USB at the same time as a backup power source, perhaps
- Tried using two different NavX units
- Tried using two different RoboRIOs on two different robots
- Tried using every data source (MXP Serial, MXP SPI, MXP I2C, USB Serial)
- Code usage is simple -- opening in Begin.vi, reading in Teleop.vi with Get YPRH block

Nevertheless, the result is always the same. Our ability to aim falls apart without a gyro, so this problem has been quite bothersome.
Can you please let me know which version of the firmware is currently loaded onto the navX-MXP units you have? The firmware for this year has resolved all known reliability issues. You should have at least v. 2.2 of the firmware loaded on the boards.
