Assuming it doesn’t overheat due to ambient temperature, the real limiting factor is the oil level. Many generators manufactures (Onan for one) recommend checking the oil “daily.” However, if you have run it 48 hours and it has not shut down due to low oil levels, then you probably just fine for that length of continuous operation.
How much oil the generator uses depends on a lot of factors not the least of which is the age of the generator. But once you have a good track on the oil consumption, or lack thereof, then you should be safe in running it more or less as much as you want consistent with changing the oil and filter per the maintenance manual recommendations and other routine maintenance requirements.
BTW, I wouldn’t depend on this "low oil" protection feature, but most “RV” Onan’s will shut down if the oil level gets too low. But I wouldn't suggest using this feature to determine when the unit needs more oil.
That’s my experience using “RV” type generators in commercial service as well as the one my 5’er.

It should say in your manual – but assuming it is an Onan and you’re operating in more or less “normal” temperatures, I use 15-40 Shell Rotella, which is way over kill. But it is the same as used in my diesel truck and therefore, I only have to carry one type of oil.
You can get the filters at NAPA. I change the filter when I change the oil.
I do recommend you spend some reading time in the manual just to make sure you’re following the manufacture’s recommendations. My Dad always told me, “If everything else fails, read the directions.” That was good advice from a sage of a man.

Well, it depends on exactly what broke in the motor. J But just a guess, nothing more without more information – low battery voltage or a bad 12 volt connection to the generator from the battery.
The starter is 12 volts. When voltage is “low” (bad connections act as a resistor) it requires more current to make the same “power.” More current (i.e, higher current) “could” damage the windings in the electric starter motor.
As I said, just a guess without more info. Sorry about that.
What did the repair guy say?
