i am having the same freaking problem with my 98. i will be driving on the highway and the car would just die i have to pull over for a few seconds and started up again...well the last time it would not start and had to tow home ..now as i turn the key to try to start it i would get reduce engine power...service engine soon..check tire presure..the check engine light would be very dim...and i cant hear the fuel pump go on so the car does not start..it cranks but does not start and one of the relay is buzzing like hell in the engine compartment ..changed it with new but no help...helppppppp what the hell is the problem???????????? 
What DTCs are you seeing when you get the reduced power issue?? Use the DIC and read the DTCs
I had the exact same issue and was ready to burn the damn car. Lucky for me and the insurance Co I figured out what was wrong.
Check out my stickey post. It will shed a LOT of light on your issue:

We can get this fixed. Between the TAC and bad grounds, you will be fine!

Since you have a 98 see if you can find someone local with EFI live. All 97-98 are free for them to tune. Have them disable the column lock feature and that should eliminate that issue with fuel shut off and the car should start. Also if you go through your codes you should see a anti theft code I forgot the number.

Mine's Locked
I have a 99 MN6. I went to move my car yesterday, the steering locked and fuel was shut off. "Pull key and wait 10 seconds" displayed. Did as instructed, did not unlock column. I tried turning the wheel while inserting key, and also disconnecting/reconnecting battery, nothing seems to work. Checked the service history and contacted previous owner. The previous owner stated he never had a problem, but had the recall performed in 2001 and reprogramed in 2004. The service history shows:
09/26/2001 0743 - ECL RELAY HARNESS REPLACE 10343 miles
12/28/2004 V1145 - 04006 - PERFORM REPROGRAM AND FUNCTIONAL TEST - MANUALS ON 26379 miles
Since it shows the harness was replaced and reprogram has been done, what should I do at this point?

I had my 2001 coupe MN6, serviced for the original recall, 04006, three years ago. I got the service column lock message a couple of weeks ago and had to tow my car to the dealership! There is the updated recall on the forum if you search for it......it's now 04006C and GM fixed it at no charge!

97 & early 98s had defective TAC modules. They failed a lot and GM issued a TSB to dealers for replacement if they caused certain problems. Its a very good idea to replace the TAC module if you have an early 98 and even a mid year 98. My 98 was an early one and I had FREQUENT Reduced Engine Power problems. If the TAC module is causing you problems, you WILL have DTC!! Read the DTCs and see if you have any. If you go into Reduced Power, READ THE DTCs before you turn off the Ignition.

Column Lock
Mine just did the same thing on Saturday when I went to visit my father an hour and an a half from home. This morning I called Chevrolets customer Service # and to my surprise they were very helpfull. They gave me the recall # 04006C, then a service request # and told me to call Chevrolet Roadside 1(800)243-8971 and they would tow my car to the dealership at no charge.

Now the dealer is trying to tell me the recall warranty only applies to 1997-2000 Corvettes equiped with automatic trans- EXPORT VEHICLES ONLY- which mine is apparently NOT
It seems they are just trying to find ways NOT TO HELP me instead of the other way around!
Never had this problem with my Toyotas.........

I bought mine used. After giving the lady I spoke with my vin # she was able to tell me that the recall had already been done on my car once by the first owner. And oh by the way mine is a M6. Keep fighting. Dont let THE MAN keep you down. Maybe you should call the same women I talked to at Chevrolet. Her # and extention is in my office. I will email it to you tomorrow. She had me on the phone for an hour but she was going back and fourth trying to help me the whole time.

Well, after numerous phone calls to GM customer service and the dealer that had my car..........GM IS PAYING FOR EVERYTHING
Moral to this story: DONT GIVE UP! When this first started last thursday, GM and the dealer were going to pay NOTHING....ZERO.....NADA
I guess I kept bugging them to the point they figured I wasn't going away without a fight. But....customer service shouldn't be that way in my opinion. I don't have a warm fuzzy feeling about GM right now, but at least I'm not getting butt *ucked for $540.00

PLEASE!!! Clear ALL of those codes and try cranking it again. See what new ones come back. You have LOTS of NO COMMS and that isnt good
NO COMMS can be caused by the door harnesses. Have you checked them??? Here is a post that I replied to that explains the issue. The NO COMMS can and will cause a NO START condition:
http://forums.corvetteforum.com/show....php?t=1750226
Examine the connector and look for bare wires.
Then try it again
