I don't know if I'd call it burned out so much as I've gotten a little bored with writing. I usually take it as an indication that I need a break, some time to refresh myself. It has lasted anywhere from a day to about 2 to 3 weeks. So I take a vacation, which gives me the much needed opportunity to feed my mind, soul, and writer's spirit with inspiration. We're talking museums, art supply stores, toy stores, fabric stores, hobby/craft stores, picnics and semi-long drives in the country (if I can afford the gas). Doing crafty or artistic things that have nothing to do with writing engages my mind in another direction. Even trips to the library or a book store, and reading other peoples' writing is stimulating. By not allowing myself to go near the computer in the mean time, I soon find my desire to get back to writing comes back with a vengeance.
