after going through a bit of rough terrain last night my truck shut off on me twice, all gauges died and i got no bus error, i took terminals off battery to reset comp as i thought that was the problem, tried to restart it and it ran fine, this would actually be the 3rd time this has happened in a span of 2 months, I just recently replaced my pcm.(as you can see if you read my other thread "electrical problems thread". it seems like after i went over some "rough terrain" and got back on the highway it did this.

 

i would check all of your grounds going to and from your pcm, motor, battery.

you might have a frayed wire somewhere that is grounding out while your bouncing around and killing your motor.
