got a new WB O2 , moved IAT out of engine bay, updated to hi-res 10g. car still gradually leans out over time of driving. If i turn the car off and back on it acts fine for a little bit but quickly does it again. Any insight appreciated

i put the factory ecu in the car and it still did the same thing. car at operating temp: it idles and accels normal for the first +/-10min. of driving. the idle and accel start to get progressively leaner and leaner until the car maxes out the afr gauge on idle at 22.4 and dies, i turn it back on and its fine for about +/-5min. it cannot be fixed with corrections. when it started doing it i turned up my ego settings and it would get better for a bit , but it would continue to get leaner. If i try to richen for it getting lean it just gets leaner and i end up with a really uber rich tune on restart. I have checked for vacuum leaks with propane when it happens. Injectors ohms are good. when i datalog the problem nothing looks out of the ordinary except the afrs are lean. this is really bumming me out i need to figure this out before i go crazy.

Yes. Gair is air temperature density correction and goes off the airdenfactor.inc file.
