Another interview question

[firedancer49]

So I have an interview next week, and I'm the frontrunner.  I was just given the heads up that I need to complete a 20 minute presentation on a project I have worked on.  The hiring manager (who I have been working with on this job for 6 months, in addition to my job) said have it be 3 - 4 slides.  His big boss is the one running the interviews, lives across the country and I have had very limited interaction with him.
I'm going to shit myself.  I have not interviewed in 7 years and have never done one where I need to do a presentation. 
He said explain the project, who the direction came from, the timeline any issues in the process and how it was completed.  He's giving me a 3 day headstart, because any other people they are interviewing are not being told until Monday/Tuesday. 
So does what he said to do sound about right?
Any pointers to get my through the 'I'm going to throw up thoughts?'

Don't throw up.
