Your problem is NP-hard, by reduction from 3SAT.
Let $\varphi$ be a 3SAT formula with $m$ clauses and on the $n$ variables $x_1,\dots,x_n$. Construct a NFA over the alphabet $\Sigma=\{0,1\}$ as follows. The $n$-bit input to the NFA is treated as an assignment to $x_1,\dots,x_n$. The NFA first nondeterministically selects one of the $m$ clauses. Then, it ...
