I'm not sure you told everyone that, so I am sharing this info.

Test your NTC temp sender for the ECU.  (it's somewhere on the engine)

Can you measure the current at the CPA (the greyish thing on the front 
of the fuel distributor)?

Obviously your cat is fine if you get power when cold.

Check your ECU grounds that are usually on the intake manifold (at 
least, I think they are on your engine...)
