Given that many others have had theirs work flawlessly for thousands of hours, and you've had two fail in very short order, the problem sounds like something other than the ADAHRS. Do you have a schematic for the plane? Have you examined all the wiring in the EFIS/EMS/ADAHRS system to look for issues, proper terminations, pinouts, etc.The original (first ) module worked faultlessly for about 130 hrs.
Second, was the loan module - for about 5 hrs or so (would have to to check log) also without fault.
The new, as stated , 4 hrs.
Have reported problem to local agents - they have asked for more information.

Basically, it's hard for people to help you without a lot more information. You swapped out parts, and the problem didn't go away, so the problem is probably not the parts (although they're a casualty of the underlying issue).
For example, on the first unit, you say "failed". But what aspect of it failed, how? A big red X on the screen, or some particular function in particular? On the second unit, you say the mag heading froze...we're assuming you don't have a remote magnetometer, but we don't know that.
The more data you can provide, the better help you'll get here.
