The cogs aren't slipping as far as I can tell. I don't hear any skipping. It feels like the cranks are moving independent of the chain, but everything is still in sync so that doesn't seem to be it. The other speculation is that the freewheel was tightening, but it doesn't make sense that it would have done that as much as is has.

This happens on the largest rear cog. I don't know if it happens on the others because it doesn't do it every time, and most of the time I'm starting on the largest cog since I have my son who may or may not be pedaling and a trailer in the back. I'm on the middle ring in the front.

If so, you will probably have to adjust both front and rear derailleurs. If you don't know how to do it, you'll have to learn or take it in somewhere.
Yes, this is mail order. I think the rear derailleur is bent because no amount of adjustment is getting it to shift right every time. I'll get it right on the downshifts, but then the upshifts don't work. I've been working on dialing it in when we stop on rides, but I haven't had time since we started riding it to take some time at home to look at it in detail.
