Hitting a wall at 4K

I had a very similar issue with my Duster a couple years back. I made two passes at the drag strip. Both times I had the car floored, over halfway down the track the car completey bogged out. Like it just ran out of breath. I thought it was going to stall. I asked about on this forum and suggested replacing the stock sending unit in the tank. The sock filter gets clogged when sitting for a period of time without being started. I know my car sat for a while at some point. We replaced the stock fuel tank and sending unit. The problem is gone. No more related issues.

Hope this helps.
