Our 96 R72 would not start intermitently. It turned out to be a small relay under the radiator(small black plastic relay like an aftermarket fog light kit sometimes contain) . It wouldn't even fire sometimes then the next time it would fire right up. I to had the cummins guy check it and put his computer on it and declare it was a loose connection but it acted up right after he left.Wallet $270 lighter. A diesel repair shop foreman told me to keep the fuel as clean as possible to prevent problems with that electronic controled box on the fuel pump(expensive,$2000CAN I think he said)
