I had a little luck with mine so far turned out to have some really bogus plugs and a bad ignition knock off ignition . I'm really rooting for you. hope you figure it out. if I can think of anything else I'll chime in again. I've got a little power issue in my 2003 SE going on intermittent ABS light coming on and off so the speedometer keeps going in and out and the convertible top doesn't want to go up and down correctly unless the ABS light is off so there's got to be a ground issue in my mind the powers back feed and somehow. But I'm wondering if it's not the ignition as well. As everybody says the ignition can do a lot of strange things. So I'll share any information I come up with on the ignition with you over the next week and I look forward to any information you have as well. Hope you figure it out soon.

The ignition switch DOES sound very plausible - I had to replace the switch portion on our 1999 SE at 226K miles. It was easier to diagnose, because the car would sometimes start and sometimes not, depending on how the key was held. The momentary "key not recognized" showed up too.

Search on "testing ignition switch" on this board and on saab net, to get advice on best points to test power.

If you do have to replace the ignition switch, be very careful with the transmission shift cable. I broke the cable at a weak spot where it passes through the one bulkhead. This can be avoided by following all the WIS steps that some mechanics are tempted to skip, and I was part of that group.
Thanks. Yeah it definitely wouldn't hurt to go over the grounds multiple times.
Great suggestions, I'll definitely check that out.

Sounds like you may need your abs module rebuilt soon?
I'm thinking once I get this going again, that might be the next thing because my speedometer was not working as well, and I had an ABS warning.

Of course, the dice unit also wasn't married, but is now, so who knows what'll be different once it gets power again, haha!

I'm not sure I'll have a chance to look at it again for a couple more weeks. I was trying to get it done for my friend to drive but, I'm 8 days away from a 7000 mile trip and I have to prepare a new-to-us, 34yo RV.

You were right on with the abs module .i replaced it and everything came back to normal. unfortunately it was a junk yard module and it's not 100 percent.i was wondering if the guys that have had them rebuilt have had longevity after the rebuild.my experience with rebuilds on electronics has been short periods until they break again like 6 to 9 months.so I'd love to hear how people have faired with tc/abs rebuilds.thanks hope the vacay goes great.
