This one is not doing a PMT, it is simply just stopping. It literally feels like it just loses all power for the forward and reverse. It happens more often when I have it running, turn the key off and let it sit over break or something, go back to run again and it won't move. That's when I can sometimes unplug the battery and plug it back in to get it to move, or if that doesn't work sometimes just continually trying it will all of a sudden start going.
I did look at the harness I believe you are referring to a couple days ago, I unplugged it and blew it out some and when I hooked it back up it started to work, longer than normal but then when i let it set turned off for roughly 10 minutes it was back to not working.
