I can't believe I didn't check this earlier but it turned out to be the disk drive I was using for this project. I have quite a few hard drives in removable bays and for this project I was using an old WD Expert 27.3GB. I believe this drive is simply not fast enough for flawless DV output of long projects. I moved the project to my WD 45GB and the audio dropout problem disappeared.
Weird thing is that the older Expert drive is 7200 rpm while the newer one is 5400 rpm. You can underestimate the importance of data density. The Expert is 6.8GB/Platter while the newer one is 15.3GB/Platter.
According to Storage Review the Expert can only do 8100KB/sec running Winbench 99's Premiere test while the new 45GB one does 13200KB/sec. That's a difference of 5MB/sec or so. Enough for the older drive to get overloaded every now and then.
BTW, the Expert didn't work even after I defragged it while the newer drive worked without defragging.
Just thought I'd pass along my experience.
