The majority of sexual abuse survivors will suffer from some form of depression, posttraumatic stress, and even anxiety in adulthood. To treat these conditions like the stress she experiences sometimes during sex, she should seek cognitive therapy with a psychologist. There isn't really anything specific for you to do but to stop the actual sexual act during those moments and console her, reminding her that you love her. In the meantime encourage therapy, do not take her flashbacks during your sexual encounters personally, and communicate about sex with each other. The fact that this doesn't happen often, is already a good sign. Best wishes!
