I have an 07 Ultra that as of late has been just shutting off for no reason. I have a Stage III power commander, rhinehart trueduals and super sucker II air intake. No other mods. I took to HD and was told my power commander cable was the problem. I picked it up and six miles later I'm stranded on the side of the for a second time in two days. Has anyone out there had this issue and waht was the diagnosis. I did have some codes on it when it went in. P1353, P1354 and three others I can't remember.
