COMMENTS

It appears that the number of zeros is infinite.
Observation: at least for the first 110 terms the largest distance between two zeros that are between nonzero terms is 3.
Question: are there distances > 3?
From Hartmut F. W. Hoft, Jun 13 2017: (Start)
Yes: a(346...351) = {0,1,2,3,4,0).
Conjecture: a(n)>=0, for all n>=0, and a(n) is unbounded.
First occurrences are: 3 = a(337) occurring 27 times; 4 = a(350) occurring 8 times; 5 = a(830) occurring 5 times; all through n=2500. (End)
