May be a long shot at this point, but I had a very similar issue when getting my Aero going. Problem was a dirty connection on the start switch and a dirty starter relay, allowing for a little to pass through but not enough to get the starter what it wanted to start. Cleaned both with a electronics contact cleaner and small stuff brush. Hope you get it figured out!

Brushes on motor can also be shot. Easiest way to test is remove bendix and engage starter. Should run very fast... if it's struggling with no load, it's an electric motor issue.

Finally got back to working on the spree today since I got caught up on the cars. Jumping the battery from a car doesn't make it run any better. It still starts off decently fast and then slows down pretty quick.

The battery drops from ~13V down to 9V when cranking and then keeps decreasing slowly from there.

The starter relay gets pretty hot when I crank it for a couple of seconds or take short breaks and then crank it over again. Could the starter relay be not allowing enough voltage to the starter?
