Could be tension related, but I have had similar issues when the needle has taken a hit, or developed a burr for some reason. Sewing through hard nylon wears them out faster too. In other words, the needle tip might be catching the tread on its' way up. Have you tried a new needle? Run the tip of the needle over the tip of you finger nail or a nylon stocking and see if it catches. There could be a burr in the needle hole too. For top stitch thread you might need a large eye needle too, size 110 and 120 sometimes are anyway, at least jeans needles. Tera 40 is closer to top stitch or extra strength? Thread weight systems get me confused.
