Besides shutting down the generator for refueling,how many hrs can a portable generator run for?Can it run for 48-72 hrs?Or should it be shut down for a certain period of time after running it for X amount or hrs??

As long as you have fuel and oil, you can run them continuously or at least as long as the duration of oil change intervals. Generators are designed to run long. I'd be watching temperatures of the generator end more so than the engine. If the unit can be kept within it's normal operating temperatures, I wouldn't have any concern about long duration runs. I know of large remote diesel generator installations way up in northern Canada that have 75 to 100 gallon engine oil reservoirs that allow them to run for many months at a time. That's why the necessity for such a large (remote) engine oil sump.
