My chain slipped off on my 3 speed Brompton - reason?
So I was on 8 miles in on a my 16 mile ride, I stood up on the pedals to accelerate from a stop then *metals crunching* the chain came off my Brommie. I think I was shifting, but I'm not entirely sure. I didn't think it was a problem with internal hubs since they don't use derailleurs. I'm around the time when I need my 100 mile tune-up. Do you guys think this is the problem?

on site inspection is best..
not many clues offered... front or back?
bringing it in for that 100 mile tuneup is the solution, not the problem..

A few years after purchase, Chain Slipping Off was the only major problem I had with my own 3 speed Brompton as well for the almost 7 years I had have it. I simply slipped back on as I was on the road, not at home. When I went home, I thoroughly cleaned the chain & oiled it again with a little squirt of oil. I examined any part of the drivetrain for damage (there was/is none) & especially the chain tensioner adjustment for possible adjustments and/or damage. There was none there as well. So far, I have no repeats of this problem. If the chain does continue to jump off, I would visit your Brompton dealer.

I was pedaling hard, had just shifted, and then hit a bump hard. I knew it was too hard too. Chain slipped off. It was the only time it happened. Doesn't sound too dissimilar to what you went through.
