I am not sure of this is the right forum however, This 1980 528 E has been sitting for approximately 5 years. Then I attempt to start it, it will turn over and start with some starter fluid and working it for some time. Then it will run for about 5 minutes, however after it gets warm then it shuts down, and cannot be restarted.

The motor was rebuilt before it sat for this time. Car is a 5 speed manual.
