Yup, I'd start putting those MAF's under a microscope.
I'm not kidding...there has to be some tell tale clue as to what's killing them. You'll see all with the microscope! Hell, even one of those $40 100x one's at Toys R Us should do the trick.

Could be the hot wire is too hot!
If it's not crud in the intake it could be the hot wire is burning out. The ECU supplies the MAF sensor with a variable voltage to maintain the hot wire at a constant current. Air flow will cool the wire and lower it's resistance, thus requiring less voltage to maintain a constant current. It is this voltage which is read to control fuel delivery. So what can happen to cause too much current to go through the hot wire and blow it out? Is it a mechanical problem with the MAF? Has the MAF been modified? Is it the ECU? Any theories? Are the failures mostly on modified cars?

There is a certain range of voltages that the MAF runs in. If you flow too much air it will spike
the voltage and blow the MAF. The way to fix this is to have a larger sampling area (larger MAF housing) The point is that I am flowing too much air (specially when it is cold out). Unfortunately you can't just throw a larger MAF housing on with out new software. Mark, AWE, and I are hopfully going to be working on fitting the RSK04 kit's MAF housing on my car with the proper software. A MAF a month sucks ***!
