A letter Michael Jackson wrote to Lisa Marie Presley -- complaining about the problem that ultimately killed the singer -- has been yanked from the auction block after Lisa Marie pitched a fit.

Lisa Marie has not said why she wanted the letter pulled, but it's pretty clear -- Michael struggled with sleep deprivation for years until he found a quick fix in the form of Propofol.

The letter -- written sometime between 1993 and 1996, reads as follows: "Smell here [arrow with box] Lisa I truly need this rest I haven't slept litterally [sic] in 4 days now. I need to be away from phones and Business people. I must take care of my health first Im' [sic] crazy for you Love Turd."

As TMZ first reported, Jackson was doctor shopping for Propofol before he hooked up with Conrad Murray.

So Julien's Auction in Beverly Hills -- the same company selling off Elvis' crypt -- has capitulated to Elvis' daughter. Owner Darren Julien tells TMZ, "I'm assuming it's a personal nature, and we wanted to honor the request and continue our good relationship with Ms. Presley."
