Check your valve stem nuts
For tightness.
When you torque your lug
Nuts.
I lost all the air just after I crossed the 1320 stripe at 131 mph
From a valve stem loosening up.

I had stems that were not torqued correctly.

They didn't come lose, but would deflect when at speeds above 120ish (which took forever to diagnose and confirm).

So I had a similar experience, crossing the one mile mark at 175 and only 20psi.

I have removed the TPMS

From my front runners.

I ordered and installed a set of the valve stems from the crate.

I assume at times I was riding on the Tpms inside the tire

As they were inverted to fit the skinny wheels.

When I lower the front tire psi down to 30 psi

To time my roll out with the lights.

Which likely loosened the stem nut over time.
