You need to narrow down the possabilities first.
With the machine parked and off, what happens when you just turn the ignition to 'ON' without starting it? Does the display come alive and stay on without your flashing issue?
If it does, that would indicate there is nothing wrong with the computer or display. You should check wiring for shorts and/or loose connections. I would check at the main connections, because you have been having to jump it, so you may have unclipped a plug inadvertantly, or damaged a wire along the way in that area.
My theory is it keeps resetting itself every few seconds because it keeps getting partial computer feed, but not continuous feed.
JUST SAYING... Good luck
