Turns out that the clutch was defective. It wasn't releasing correctly. My Ford dealer called the Ford service hotline and they confirmed that this is an identified problem on some Focuses. Replacing the clutch was the only solution. They got a new clutch kit from Ford and completed the repairs in a day.
Just got my Focus back today and the problem is resolved.
Glad it was fixed! Looking like this will need to be done sooner or later to mine as well. It still works pretty good and sometimes doesn't even slip, usually under really light or really heavy acceleration it works fine. But from a stop with medium acceleration; about half way thru 1st gear it will start slipping and I will feel the shudder again right before shifting into 2nd and occasionally it will have a strong lurch or harsh shift into 2nd. I havn't noticed if it's worse after warm up ... seems like it happens randomly all the time regardless of hot or cold. The rest of the gears shift normal but I get a random lurch once in awhile in the upper gears as well but no slippage that I can tell.
I will have it looked at by the dealer to see if they can confirm there is a problem.
