One of the statements in my paragraph may have been misleading. My car finally started and the radio did start working. I don't understand why the car did not crank with the first attempt on the new battery though. Sounds like it wouldn't be related to the battery protection relay.

Re: 2000 Ford Expedition Engine/Radio problem
Most likely the issue is the battery protection relay, it may have been set off by a sticking courtesy light switch on the door latch (very common), this would have kept the dome lights on after u left the truck, this would have triggered the relay after about 10 minutes

Mine had a similar problem (radio/tape casette days a 2 decades ago) Had to return the radio 3 times till they finally fixed it correctly. It was a problem internal to the radio. Sounds like you may have a compnent loose & not soldered well to the PC board. Or maybe it's a bad component & got fried. (output transistors ?)
the starter relay is on a module conected to the radio relay....the starter must be cold when starting or it will not start in this problem on this vehicle....in other words you have a bad starter relay.:)
