Tesla Motors Club

So my Roadster ended up cutting out this week. Roadster has been sitting for months at 60% SOC. Made it into work fine which was 35 miles. About 8 miles into the trip back the Roadster's power shut down and I ended up with the following faults below. I did a key reset after waiting 5 mins all to have it cut out again on me. Had the Roadster towed home and issue still exists. Removed and reinserted all the cables to the Silver High Voltage controller that's under the front hood (Silver box with cooling fins). Also removed the ESS cables and reinserted them. After I did that the Roadster now complains about the left headlight and tail light being out, which they are not and working fine.

I did wash the Roadster the day before I drove it. Water did end up on top of the PEM and battery top. I ended up grabbing a towel and wiping that down. Charged afterwards fine as well as charged in the morning fully in standard mode.

Curious any ideas or clues to debug this one?

I included some snap shots of my voltage, SOC, etc as well. The odd thing is that my Vess value under the BSM screen reads "0V". Curious what others get for that value, in particular 1.5 owners. This is with the key in the off position.
