It is likely that the maximum mempool unconfirmed chain limit is exceeded at those time. At that point, no more transactions can be created (with those UTXOs) because the local mempool wouldn't accept them, let alone other nodes.
If you are creating long transaction chains it might be preferable to batch sends and send them at once with sendmany. This is more efficient in regard to block space as well.
Thank you
