You have forgotten one salient piece of information..

what car is it?

I'm guessing it might be a 924 or 944 but have left my crystal ball at the office

Try a new battery - or a DME relay.

what does the dme relay do?

It's more than likely your fuel accumulator, it's next to your fuel filter on the left hand side of the engine bay, when faulty it causes vapour lock in your fuel head and makes hot starts a bitch, cheap easy fix
