Could be low coolant, but most diesel motors are set to shut down if that occurs. You could have broken a fan belt, you could have a bad thermostat, or a bad water pump. The engine fault codes might be able to pinpoint it for you, as well.
Depends on WHICH Cummins engine.
No Cummins INC company makes the Cummins engine.

Most people say that Cummins is the best diesel engine but not with the new 6.7L offered in Dodge Ram trucks. The Ford Powerstroke Diesels put out more power than the Cummins by 40 horsepower and 85 pound feet of torque. Also, the new 6.7L Cummins engine has been known to overheat, stall, and the turbos are blowing in them at around 30,000 to 40,000 miles. The Cummins can't idle for more than 6 minutes or it will overheat and shut off and you must take it to the dealer to get the problem fixed. Let's compare. 6.4L Powerstroke diesel does not overheat, does not stall, but there ARE turbo problems with them. But that is no problem with the new 2011 6.7L Powerstroke diesel. As for Duramax, they've always been behind in quality but not power. So I'd say, here in 2010, that Powerstroke is the BEST diesel engine available in a pickup truck.
