Sorry the late post guys. Got everything sorted out (I think).
I took it to the local dealer and the tech said he's seen this before and that it was just some loose wiring somewhere in the shifter assembly. He tore the whole assembly apart, cleaned and greased everything and put it all back together.
There was nothing noticeably wrong with anything, but it appears to have solved my problem.
That's two wiring issues in two weeks causing my SST to act up. I'm slowly losing faith. But running strong for the time being.
Good news and excellent that there was no piece of equipment damaged.
