Hi: I want to thank everyone who had input. I really appreciate it.
I replaced the start relay JD part AM123716 and it fired right up and it will move. HOWEVER just like 9973720wb19 suggested now I have to release the parking brake SLOWLY.
It is fixed just in time, that only now is my wife saying that the grass needs to be cut.
I am declaring victory and going home

good to hear. While I feel for you with this issue, I'm kinda glad a stumbled on this thread. I thought I was all along with this issue. I think there's something wrong with the design with these 997s made within those years. I just put up with mind and enjoyed it's ability nonetheless.
Hi:
Well the lesser gods of John Deere are not about to turn me loose!
After posting about my success I went to start up the 997 and it started fine. I released the PB and then the drive levers and got about 100 feet and it quit.The mower would not engage at all. I was able to get it back to my repair area.
It started doing the same thing after all of my work. I got out the operators manual which I found in the Netherlands to check all of the relays. The first relay looked different then all the others and was called a "Seat Delay Module" . I started it up and disconnected that module and it continued to run. I took the the parking brake off, the levers off and pull out the PTO switched and everything worked perfectly. So I went and mower for an hour without any problem.
I am not declaring victory only a truce for a while.

No problem on disturbing the wife; she'd be glad to do it for 'ya., but now it's moot anyway. Glad to hear you got it figured out mostly.
What do you have into relays etc, if you don't mind my asking? How'd you narrow it to the start relay?
Can't figure the slow brake release thing- that's really weird....
UPDATE: the gods of the lesser JD turned. It ran for ten minutes and stalled out. In that time the PTO would not work. I got it to the work area and thought that it was another relay. Everything else in the equasion is new and works. I got the ops manual that I got on line from europe and read the full 21 relays, diodes and modules descriptions on the sheet. I noticed that Number H Start Relay is new but Number "A Seat delay Module" is old.
Maybe member 9973720bw19 should try my fix?
I unpluged the wires on the modele A. I tried to start it and it started up fine, no problem with the slow pull on the PB, no slow pull on the levers and on moving the PTO works fine. I mower for and hour with no problems. That must have been the problem all along. The module was sending a signal that the seat had no operator present even though the switch was by passed and shut the unit down. The new start relay helped but the module over rode it. Evidently you don't really need the A module.
Go figure--- I am not a JD fan- for $20,000.00 for a new unit, they have to offer a lot more than this crappy model- in my humble opinion.
Lets see what tomorrow brings.
Originally, I got into the relay because after switches that is the next electrical items which control the unit. I have no multi meter so I just read what the relays are called- and it worked.

You may have a bare wire grounding out somewhere.. not easy to find. but easy to blame it on Deere.. 
Have you owned it since new?

You must have missed his post where he bought it used from a Town or similar who bought it from overseas or similar, I don't recall all the stats, BUT it's not new.
Hi:
It back not running, stalling out, but able to start up immediately and run with mower for 5 to 10 minutes.
Its a 2008 model and I bought it used in 2016 with 1668 hours from a city govt. which was going to 144' mowers to save on labor.
Tomorrow I am going to try and interchange the relays and see if one makes a difference.
I have a JD 238Xd mower that is old as dirt bought it 3 years ago and it runs fine. The transmission has been winning since I bought because of the clay JD grease in the tranny.
JD has a reputation for not standing behind their L&G products like the Kawasaki engine with the plastic cam gear. JD did not step up to the plate and let owners replace engines with few hours but out of warranty. Profit before reliability.
True this unit is 9 years old. It has a major design fault. It has more wire looms in it then my pickup and it will be an impossible task to find a short. A color wire goes into a loom is spliced into 2 wires each a different color and come out five wires, for example.
I will try the remaining relays first.- it only has 10 of them, 4 diode modules, something called latch relays, 2 of them and 5 fuses which are all ok and not blown.
There are 20 electric controlers lined up on the fire wall each with it own, individual bundle or loom of wires in and out. Wait found another diode in the control panel. I let you the owners decide if this is over kill. Over and out
