Multiple codes - all happen after a fast acceleration
Basically, after accelerating very hard, a check engine light sometimes comes one. This has happened about three times in the past year. The codes go away by themselves without a reset.
After running the codes, the following all come up.
B2282 H
B2283 H
B2284 H
B2285 H
B0367 H
U1255 H
After researching on Corvette Forum, the first four seem to indicate a grounding fault, but I wanted to get any other advise on what to begin checking.
Thanks!

None of those codes will cause the Check Engine Light. Were there any other codes that you did not list?????? Nect time the CEL light comes on, pull over and pull the codes BEFORE you shut off the engine. To pull codes with the engine running use the reset button to remove any warning messages in the DIC and then pull codes as normal. Pos back here ALL the codes that you have.
First thing I would do for the other codes is check the battery connections at both battery cables and also at the starter solenoid. Make certain they are clean and tight. The first 4 codes are usually indicative of a battery or power related issue.The B2282 and B2284 are for the drivers side door control module and the B2283 and B2285 are for the passenger side door control module.
If the battery connections are good then the problem may be related to a black 6 wire connector inside the A-Pillar.
The first 4 codes and the U1255 may be related. Read through this thread for more info about the black connector in question:

Pull back the accordion tube and then fish out the blue and black connectors. The Black connector has a presence of the Serial Data Buss and if that pin looses connectivity due to vibration (yes it is as simple as road vibration) the U1255 code will get set. The other 4 codes get set due to loss of power to the door electronics. Disconnect the battery before attempting to reshape the pins in the connector as there is also battery power in that connector. There is an identical plug on the passenger side and I suggest that you check BOTH sides.

I'll go check out that thread. Appreciate it!
