    I had that problem with my 1999 GMC Jimmy. I found out that it was vacumn line that runs over the transmission to the ATC. It had a small cut and when the engine warmed up it expanded the the cut and was no longer able to hold the vacumn. It would then blow the fuse of the ATC. Try there. Hope it works for you.
