When I floor my car it shuts down. The wheels spin for a bit then the car feels like it goes from horsepower to no horsepower. I can not find a dtc. Has anybody had this happen and what is going on?

Here

Need details on the car. Mileage, tranny, mods, etc...

THROTTLE BODY SPACER/AXLE BACKS/4.10's/JLT SERIES3/SCT TUNE. About 97000 miles and everything else is stock. 2007 Mustang GT 4.6L. And going to a shop first thing in morning atleast gunna try and get there or have it towed in? What ever you think I should look at would be helpfull and I thought it was the fuel rail pressure sensor and had it replaced but does the car have 2 one left and one right? It has an Automatic Trans and once I get it fixed it might be for sale in the Dallas Tx area?

If you've got no DTCs, I'd assume all of your sensors are plugged in and at least working. Hard to diagnose something like this across the internet, since the issue is pretty general, but to start you down the right path I'd check for:
-vacuum leaks
-transmission health (could be a failing torque converter at WOT)
-fuel system health (when was the last time you changed the fuel filter)? Could be starving at WOT
-catalytic converters- if they're bad/clogged you would experience WOT issues.

Too much torque causes a ripple in the space-time continuum, which makes it feel like nothing is happening for a moment.

Is there a way for you to check voltage to the TPS sensor and the fuel pump? What about fuel pressure? I'd start there.

Towed in? So...It's either having more issues than what you're describing, or you can't drive it without spinning the tires everywhere you go.

Is it tripping the check engine light? Codes? What does it do when you drive normally? No, it doesn't have two FRPS's.
