Did you open a new pack of needles? Check to make sure the needle length is right for your machine. Put white thread and a different colour in the bobbin and do a zig zag stitch. The zig zag will tell you which thread is acting up. Clean and check both tensions. If you've done all that perhaps the timing has been set off and it may need a trip to the machine doctor. Maybe someone else will have other suggestions.
