Do you mean that you lost power when you wrote “lost compression”. Compression has a specific meaning wrt to internal combustion engines.

The engine started making a noise, lost power, and died. Did it run out of gas?

what sort of noise was it making? was it ticking? was it knocking?  
How do you know you lost compression?  
have you tested the compression on all of the cylinders?  
did any warning lights come on before it died?  
did it start missing when it died?

For a non-Ford guy what engine are we talking about? A overhead cam V-8? Plugged oil pan? you mean plugged the pick-up screen on the oil pump? I would like to figure this out for you.

This was the latest attempt to revive the Cougar name. It was an FWD sports coupe with either a 2.0L four or 2.5L V6 engine.
