oil pressure drops to zero
oil pressure goes up to 30 on start up, but after about 15 seconds it slowly drops down to zero. i checked the wire from the pressure sending unit and it looks clean. any other thoughts where i should start

You have a few options here.
1. Ignore it
2. Use sandpaper and clean the terminal on the sender
3. Replace the sender
4. If oil pressure is important to you, get an aftermarket gauge
Keep in mind the stock oil pressure gauge isn't all that accurate or useful to begin with. I wouldn't stress over it all. I'm also assuming you're talking about an fd.

My biggest question is what weight oil are you using and what are the temps outside right now?

I have had to replace the pump on more than one of my cars due to oil pressure acting as the OP described. The FC3S are 30 year old cars now. I wouldn't say it's nearly as rare as it once was. The first time I made a mistake assuming my gauge was simply faulty and wrote it off. This lead to a short lived engine that burned lots of oil due to excessively worn oil control ring carriers.
To the OP: If it's determined to truly be low pressure, go by the procedure in the FSM to check the pump clearances with the feeler gauges. you may be surprised how out of spec it is. Perfect time to upgrade to a turbo oil pump if you see fit.
