2G MAF issue

Hi gurus,

Just wanted to pick your brains, may be someone had similar issue. The engine quit on a very hot day (well, we were running it quite hard to be honest). Symptoms of running on 3 cylinders, but with no power whatsoever. It appeared to be a MAF supplying twice as much frequency to ECU. Say, instead of 50-60 Hz at 1200 RPM it would tell 150 Hz. Engine was running too rich. Disconnecting the MAF fixed the idle (ECU goes into default mode), obviously MAF has to be replaced. However, has anyone of you played with MAF internals? I mean the board itself, may be it has some known weaknesses? Capacitors, not heat-sink for the transistors and etc?
