Loss of power momentarily ISL 380
While driving down the interstate we suddenly lost power and the gauges went back-and-forth this only happened 2 times and it was like seconds then the power came back and we went on down the road this is on a 2014 Phaeton ISL 380 Cummins engine I stopped at a Cummins shop and they say it sounds like a wiring problem they couldn't look at it now so I went on down the road. My question is has anyone else had this kind of problem?
Thanks in advance
