That's how I use it.

That is very short but I haven't had much experience using full  
throttle. Most of the time I loose the belt earlier then the 45  
seconds ;-)

The the engine can't have been very hot because it did stop at the  
same time I turned the engine off. Maybe it had already cooled down.  
Like I said, I didn't find the engine very hot sticking my head in the  
engine bay. Maybe Bob Helts remark on the wrong temperature switch  
could be correct.

Somehow I think it wasn't really overheating. It ran way to smooth too.

Just check it and it's on as is the vacuum/pressure line to the turbo  
gauge on the dash. Any more ideas where there could be a vacuum leak  
and how to check for them?

Not sure what DAMHIK means but I guess it's better to solve the  
pinging first before pushing it :-))
