I don't think the problem lies in your DIC, sounds like a wiring or alternator issue.

If everything is re-setting after your turn the car off it might be a battery issue also. I would test your battery and alternator, if that doesn't do the trick maybe start looking at your wiring harness. I do know that not having your wheel bearing sensors hooked up will wreek havoc on your TCS and DIC readings...so make sure all 4 wheels are hooked up correctly and the wires are in good condition
