This is just a shot in the dark...
But, since you get very strange things going on with your gages as the RPM's come up... your voltage regulator may be bad. If the voltage gets above 14v ~ 15v... the computer is going to do strange things. (or burn out)
it could be anything really... but that's my guess.

I agree with Dr. Honda...
Check your voltages. Best tool would be an oscilloscope, next best would be an analog voltmeter. A digital multimeter (under $5 at Harbor Freight if you don't already have one) will do the job but won't show fluctuations more rapid than its sample rate. Still better than nothing, though.
Does your engine vibrate more when the problem occurs? You may have an intermittent ground which gets rattled by engine vibration. The result would be noisy power to the ECU and other systems, not a whole lot different than bad regulation. I mention this because you said the gauges "flicker", which I interpret as meaning their illumination goes on and off. That's more likely to be a grounding problem.
Report back... let's get this fixed!

Thanks for your replys, I am looking for any direction I can get. I am not sure if it happens due to vibration or not. What I mean by flicker of the gauges is they pin all the way to the max and bounce for a second before the engine shuts off completely. A couple of times yesterday the engine wouldn't start right back up. The radio and all electrical still worked, but there was nothing at all when I turned the key. Then a few minutes later it would turn over without a problem. I would try to excellerate even just a little bit and it would cut out again.
