Unhappy

I need help. I have a 96 Camaro Z-28, 5.7L. It has a few after market parts. MSD ignition, headers, chip. The car was running very good. My son was driving and hit a bump and now the car will cut out every time it reaches 3000 rpm. It is not just a miss, it seems like the whole car shuts down, but does not stall it just won't go above 3000 rpm when being driven. If you are sitting there it will go past 3000 while revving. Also if you are sitting there and take it up slowly as it hits 3000 it will drop to 2800 then surge back up to 3000 and repeat. I changed the MSD ignition box and put a brand new one in. I had the chip and computer checked and was fine. I've tried running it with out the Mass airflow connected and it does the same thing. I had the local Chevrolet dealer check it and they can'y figure it out. Is there someone out there that can help or at least has a few new ideas. Thanks

If Your car is an automatic....I had a customers car act similar once...it had a bad neutral safety switch...the computer thought the car was still in park or neutral and would cut the pulse to the injectors (rev limiting) the same as when "top speed" is reached...I imagine the same thing could happen if the starter cutout switch was bad on a manual trans car....the best way to have this checked is with a scan tool....there are many posibilities....with Your description this is just the first thing that came to mind.....Good Luck....
