Any Porsche specialists near the Arctic Circle?

Hi all. I'm looking for help in diagnosing some gremlins in a 1989 944T. I'm currently in Lapland in a 'Nordkapp or bust' spree that, at this stage, seems to be going in the busted direction.
First it died when I had a break after a 2 hour trip. Left the engine idling and after around 30 seconds it just shut down by itself. Tried to restart several times. Finally managed to start and drove to the nearest town (around 1h30) with no more problems. There I noticed the idle was very bad, going up and down between 600 and 1400 rpm, always on the verge of stalling. After a bit it finally died while in traffic. Tried to restart again several times, restarted with difficulty, drove some more meters, and died again. Again tried several times and finally picked up and run perfectly after that.
Decided to rest for the night to try to find a shop around in the next morning to check it. The next day it started at first and I did 50Km around to check if the problems reappear. As it did not, and as I imagined it would be difficult to diagnose anything without any more symptoms I decided to carry on. Did around more 300Km with no more problems. Then it started to have momentary stalls now and then, until it finally failed. Did the routine of trying to restart and drive more to reach the next town but after some time it finally went away definitively.
I've tried the spare DME relay with no change. When trying to start the crank turns OK and there's the normal smell of gasoline. Sometimes it runs for a second or two but then dies again. When it was working at higher rpms the engine was just fine with no power loss noticeable. It's been serviced regularly without any previous injection or ignition problems. Does this kind of symptoms ring any bells to anyone?
Monday is going to be checked by a local garage, arranged by the travel assistance company. The nearest OPCs are +1000Km away in Stockholm and Helsinki.

Just some simple advice - if the tach drops slowly when the engine dies it's probably a fueling problem and if the tach drops like a stone you have an electrical problem.
Battery cables secure on both ends. Can you jumper the fuel pump to ensure it runs on demand? Coil connections secure?
