Brand new nelson tractor sprinkler runs for about 20 minutes and then stops. water pressure is fine

My sprinkler did (something like) this a couple of times (very infrequently) - the arms seemed "seized" (cannot rotate clockwise or counter clockwise) but, I was able to get them moving again by picking up the sprinkler (a couple of inches) by the sprinkler arm T-pipe. Picking it up this way, vertically, seemed to "un-stick" the arms.

Of course, if your sprinkler is very old (12 years?) the gear box may be worn, it would cost about a quarter to a third as much as a brand new sprinkler to replace. You can find the parts you need by reading the question about where to get parts at FixYa.
