Twisted pair is remarkably immune to interference.  Back in the early 
days of local area networking for PCs when I worked for Novell we were 
developing some network cards and comparing performance over ethernet 
cable (which used to be coax) and twisted pair.  The coax would quite 
often loose packets when the soldering iron was placed close to the reel 
of cable we were using as our test.  (Those soldering irons that have a 
thermal cut-out built in.) Twisted pair took all manner of abuse - we 
could even run an electric drill with worn brushes next to it.

The fact that your drop-out runs for variable lengths of time does 
indicate that there is probably a co-incidence with some sort of human 
activity if only you can work out what it is.
