Thats pretty trippy!
the thud thud sounds like water hammer, this can occur when you have a loose stem or washer in a fixture, but the reduction in pressure sounds like maybe some obstruction is partially blocking a section of the hot water piping.
Maybe stuck at a reducing tee, and slamming back and forth from the larger side to the reduced side of a tee.
I would try back flushing the hot water line back to the water heater.
This should work, because the hot water piping will INCREASE in size at it is blown back to the heater.
shut off the cold water inlet to the water heaterttach a hose to the drain, run the hose to a safe place to drain.
remove the hot side hose from your cloths washer and the stop, and disconnect the cold hose from the washer ONLY and connect it directly to the hot stop.
now open the drain of the water heater, and turn on the cold stop of the washer.
this should blow cold backward through your hot and hopefully flush whatever it is safley out of the drain.
If it doesnt work, look at the bright side…at least you flushed out your heater!
also, you may want to check your pressure regulator..(if you have one)they do some pretty weird stuff sometimes,but if it ONLY with the hot water dont bother checking it.
hope that helps.
Bruce.
