Cat 329 keep cutting off

I’m also working on a cat 329 the serial number is CAT329ETPLW00668 it will run for a while and then it just shuts off, then it doesn’t want to start for a while. When it does that my diesel laptop loses communication with ecm. Last week when I went out to it, I found the intake pressure sensor wiring melted and stuck together, and the starter solenoid wiring melted and also stuck together. I cut out the bad wires and pigtails out and replaced them, but I’m scared the ecm might be screwed up now. Can y’all help me get a wiring diagram for the ecm connectors. So I can check the power to the pens. Thank you guys for the help and for any advice
