Sorry to horn in on your post Robbie, but I MUST have this problem too on my 951.

It runs fine, sometimes the windows will roll up, other times not. The cooling fans have been tested- they work fine, the thermofan switch below the top radiator hose replaced AND the cooling relay replaced ($$!). Sometimes the fans will come on if you push the AC button, most times not. The car will be running and just shut itself off, like you turned the switch! But it will start right back up again if you turn the key! My wrench says it is possessed!

I told him to check the grounds and he says they look okay. I told him to take them off ANYWAY, wire brush them and (maybe?) put some dielectric grease on them. But where are they all? I know about the negative from the battery. The strap from engine/bellhousing to body, one smaller in center rear behind carpet. Others? Other ideas what is causing this? Any help appreciated.
