I had the same exact problem with a 95 prelude. Long ass circular ramps, especially ones turning to the left at high speed seem to make all the oil move away from the oil pickup and thus creating a drop in pressure. First check the oil level, if it is fine, then pull the code. Most likely, you are going to find that you are just over driving the car. Do you have an aftermarket suspension on it? or just the sway bar? If you have the stock suspension, I am guessing the car moves around way to much and u should just slow down.
just my 2 cents...
