Last month I bought a 2005 Monterey 38ft with cat 400 engine with only 8K miles from owner that bought it new. I drove it home the 900 miles with no issues. On trip today the engine would lose all power and the Tach, speedometer, voltage gauges would all drop to zero for one to three seconds and then all would come back to normal. The ATC light would come on and stay on for a few minutes. This happened several times and without any input or change from me that I can trace it to. Seems to be electrical so after third time I stopped and checked connections on Chassis Batteries etc. I have been motorhoming and maintaining my own for 30+ years but this is my first diesel so any help pointing me in the right direction would be very much appreciated. Wondering if anyone else has encountered something similar to this. I plan to clean all terminals and carefully check batteries and connections tomorrow.
