That sounds like a sequencer issue. I've never seen one fail before, but if the jets are working for 10 seconds, and then turn off, clearly it is working. Typical changes between the sections is 15,10, or 5 seconds depending on the speed you have it set, and I think 5 of the 6 sequences all start with the neck and jets.
Does it just never come on again? Most sequences have 4-5 sections, so if it turns off after 10 seconds, give it another 50, and it turns on again.
