I wish I'd searched the forum before posting, but I'm having a similar problem, just at a lesser extent.

I only seem to lose items that contain things -- for example, buckets and energy condensers.

I must have rebuilt about ten condensers before I finally figured out where they were all going.

Also, Lapotron crystals lose all their energy if left in an ender chest when you travel between worlds.

Not sure if it matters, but I have 7 different types of ender chests and seven ender pouches corresponding to each colour. The ones in which I kept losing my stuff in were NOT connected to any pipes of any kind.

Edit: (Also, I'm running Windows XP rather than Windows 7...)
