what different motor computers would work with my 1999 ford taurus se?
None. You need the correct one. Use your VIN to search for the correct computer.
1999, your going to have problems finding that one, hopefully the one you have has numbers on it, try a wrecking yard for a good used one, if that fails check with a parts store, there maybe an R&R system in place, that's where you send in your bad one they overhaul it, reset the chips and send it back to you. What make you think you have a bad ECM?
It starts and runs but once it gets warmed up it shuts off and wont start back up until it cools down.
That sounds like a ignition module and a distributor stator failure. Do you have an IDM code when you check the codes, sometimes you can get that code but not always, so if the ignition module and stator have never been changed then now would be a good time to do so.
