A little worried.

This is just a guess based on what I already know, but, should a snake go into shed during the process of weight loss, I would think they could "pause" the shed-cycle, seeing as the old skin is no longer tight or too small. That could be a load of hooey, though. Or perhaps he doesn't have enough energy to finish the cycle.

However, on to the real problem. What prey do you normally feed him? If F/T or anything other than ASFs, try giving him a tasty little soft-furred to get the wheels spinning. However, I'd only suggest this if you have easy access to ASFs. He may get addicted.

Lastly, should this fast continue for another month or two and he starts getting progressively worse (we're talking really triangular), you may have to consider assist feeding. It's ugly, but it could very well save his life.

I don't have easy access, but I order them online from a trusted source whenever I deal with a problem feeder, but I have a couple left still I'll try on him. I really don't want to force feed, it's not fun for me or the snake, so I'll hold off until his skin sags.
Would be interesting if they could "pause" the shed cycle, I've never seen it before, but there is always something new to learn.
