Default Bike cutting out/dying at speed, runs good when cool

Hello all, I have been away for a bit, but am back! Sorry for the absence! Went for a ride yesterday, I was hauling a$$ a bit, 90+ for a while, and the bike cuts out, and shuts off. The weather was a little warm, but not screaming hot. Both cyls, just off. I coast for a bit, turn the key off, and it starts up, but cuts out, misses, and I limp it to a gas station. (the fuel light came on about 2 miles after I filled it up), it takes a gallon of fuel only. It starts up, and runs fine for the next 2-3 hours, at mellower speeds, in the mountains. Then coming home, again, around 90 MPH it does the same thing, dies, cuts out sputters. I am thinking a TPS or CPS is going out, failing when they get hot? I leave it sit, cool off, and it runs fine. 50,000 miles with a Ivans flash and PCV map, I have gone over all the wiring to assure there is no rubbed wires. The fuel reserve light comes on early, but I do not think it is related. I noticed the gauges were on after it died, I saw the tach light up when I started it. No codes come up in the internal check. Any ideas? Thanks!

Are your dry breaks completely seated? Good time to check it out.

What he said ^^^^ disconnect the left side dry break and squirt a short shot of WD40 into female half then gently reconnect until the audible click tells you its home. Do same for the underseat dry break, and make certain the tail of the fuel tank is not pinching the tank-to-tank vent hose.

I feel like someone had a very similar problem in the last few months.
