I don’t think the battery situation can be stressed nearly enough. If I don’t drive my car often enough I get that occasionally. If I drive it 3-4 times a week at least 15-20 miles, then I never get the warning. This is with a known good optima yellow top.

I used ABS Fixer several years ago repaired and not had a problem since. Check this website out.

That was my impression. I would make sure which generation EBCM you have, <just> in case there's an overlap or other anomaly.
I say that because I repaired the one on my C5Z and knew nothing about it other than to remove the module and look for the compromised solder joints. There were 5. I touched them with an iron and the codes left immediately.
The VERY biggest pain is getting the thing out. It's very hard to see and for me tough to distinguish between the mounting bolts and the actual unit's bolts. Ended up with lots of cuts and scrapes but well worth the equivalent.

I want to thank everybody for the suggestions and help. I really do appreciate it.
OK, here's the latest.
Since battery was mentioned a couple times I went ahead and did a full charge on it. I drive the car several times a week and it always starts right off and there are no indications of a problem with the battery. I don't think that was the issue.
I checked to be sure all the wheel sensors were firmly attached as well.
I started it again. Got the usual messages, service traction system, service ABS and service handling system and the skidding car icon was lit. So I went into the DIC and found the code 28-TCS-1243H. There were no other codes.
Without clearing the code, I started it again..... no messages and no icon light!!!!
I have no idea what all this means, and who knows if it will show up again, but I'm glad right now.
I did look up the code meaning, and it says BPMV motor pump stalled. I'm guessing that is an ABS pump and probably nothing can be done about it.
I'm still open to hearing any more info regarding this situation, since I can't be the only one this has happened to.
Lost in C5 land, signing off.

You could probably benefit from manually exercising the pump, or by just forcing the car abs to work by locking up the brakes on a wet surface. I’ve seen several write ups on how to manually exercise the pump and several people reporting good results

Your ABS has stalled and like dbgoodwin said, you need to exercise your motor periodically. This happened to me and now I exercise it using my Tech II every 3 months. You can do it other ways at your own risk. This fixed my problem over 5 years ago and haven't had an issue since. Good luck.

Well, I just went out and "exercised" my ABS by slamming on the brakes at about 60mph several times. A few chirps from the tires, but stopped pretty quick. Seems like an ABS response. It didn't lock up all fours or swap ends......no more messages either. I'm good for now....

I've had the lights come on a few times on my 2000 with 21K miles. I clear the codes, and make sure I "exercise" the traction control and ABS pretty much each time I drive it. I do a couple of hard 1-2 shifts for fun chirping the tires kicking it in, but I also usually dump the clutch a few times on my garage or pole barn smooth slick concrete floor so everything kicks in. I've read on here that wet grass works well too.
