Seems to have been some sort of wiring issue. I am not sure why the .9x firmwares seemed to be effected more by it, maybe it was just coincidence... But after the car stalled again at the end of my driveway (it pitches down hill, so something must have moved) I played with the harness a bit and it started up. So I inspected the whole length of it and found no chafing, but I have secured it a bit better and I haven't had a trigger error since, with .95. So I guess that was it.
I bought the universal harness from the vemsshop, and it was a good move at the time, its really quite awkward because the wire lengths are not right, it doesn't fit in the stock wiring path and the main section, with all the wires packed together is well over a foot too long... So it might be time to build my own. It would be a nice side project while the car is still operational. It would be nice if you could specify the length for each circuit/sensor when you buy it.
