T680 Electrical gremlin.

I have an intermittent electrical problem in my T 680. Usually it will start just fine although it always draws so much power that it shuts off the QUALCOMM and makes it reboot. I took it to an electrical specialist last week and he said that there's nothing they can do about it it's just a problem that half of the T680s that he has looked at have had. That is annoying but I can live with that. Yesterday when I went to restart it after fueling it did like one turnover of the Engine then the dash went blank and then another single turn over a couple of seconds later and again the dash went blank. I turned the key to the off position and tried again and then it cranked really slowly and finally started. The dash indicator then read that it had a transmission fault and the service light by the gear selector started flashing. I shut it off and restarted it and It did a little bit better starting but the fault did not correct itself so I shut it off again and turned off the two electrical shut off switches behind the driver seat off for a minute and then I turned them back on. If then started just fine with no fault indicated in the service light quit flashing by the gear selector. It started fine four times today but I do not trust this truck. It seems like every time I shut it off and turn it back on I'm rolling the dice. If I have this problem on a hot day and it doesn't restart It could get very uncomfortable. In the last month I have taken it to the TA twice to check the batteries and put on a new starter motor. I suspect the problem lies elsewhere. Has anyone encountered this problem and if so did you ever find a solution?
