Multiple Error Messages

My car went crazy today! 03 with 25K miles and no previous problems. The following messages were displayed. "check gauges", "service engine soon", "service active handling", "service tire pressure monitor", "service traction control", "shocks inoperative", "do not exceed 80 MPH" and there may have been a couple more. I turned off the car and when I restarted it, everything was normal, but about a mile later, the same thing happened. The oil pressure gauge went to 0 and the temp gauge maxed out temporarily then they returned to normal.
I did a search on this, but only found info on some of these messages. What should I look for or do??????????? Thanks for any help.

Took the connectors apart, they all looked good. No corrosion, etc. This is driving me crazy!

Pull your codes from the DIC and post. Be sure to include the "H" or "C" at the end of each one.

P1626 Theft Deterrent System Fuel Enable Circuit
U1255 Serial Data Line Malfunction
U1040 Loss of Communications with TCS

U1064 Loss of Communications with BCM
B2252 Key Cylinder Switch Fault
B2282 Battery #1 Fault
B2284 Battery #2 Fault

Stopping there with the codes. My first thoughts is your serial data buss line has issues in one of the door accordian tubes. There's a pin/socket in the connector there that can get lose and cause lots of this to happen. Also, how old is your battery? Do you have a meter and know how to use it? If yes, please measure your battery directly with the ignition off. Looking for a miniumum of 12.5vdc

Is your battery original? If so sounds like it's on it's way out. I would start there before I went any further. If the car can crank, clear out all the codes and drive the car and see what codes are thrown. Then start trouble shooting.

Battery reads 12.25vdc. Car cranks and starts good.
I drove the car approx. five miles this afternoon and everything seemed normal. Will check and see if codes reappear. I checked the buss line in the drivers door and everything looked like new. Will do the passenger door tomorrow. Would .25 volts make that much difference? Shows 13.5 on the DIC for charging voltage.
