It will not run out of gas. But it can - and will - get damaged if sitting unattended for too long.
It might be the tires (check your owner's manual!), it might be the AC (again, manual - it should be turned on from time to time), you might now notice a strange smoke due to new oil leaks inside the combustion chamber, it might make horrible noises for a couple of seconds (because the oil drained to the bottom of the engine), etc, etc.
Hell, last extended trip we went on, we had someone to start the engines (and the damn AC) for a few minutes at least every week. It is just good practice.
If indeed the battery management system on a Tesla is able to keep the batteries alive for months at 0% reported charge, then it is a non-issue. Noone is going to leave such a car unattended for months, really. Specially if it is a Roadster.
