2004 STi

Default P0011 and P0021 Only when Hot- Tried a lot of fixes

2004 Subaru STi
Dom3, spearco intercooler, 740 dw injectors, stage 1 P&L block, TBE, P&L 44mm EWG, P&L intake,
5000 miles on new motor. DD miles without street racing or autocross. Only a handfull of redline WOT pulls to 75 or so.
I will check into the oil pickup tube failure today.

I only have this problem of dying and the codes when I have been driving for more than 10 miles and the car has been at operating temp for about ten minutes or more. The car runs great for the first ten minutes. It will idle fine when it is hot, it is only when coming down to idle from driving that it will sometimes die.
I have tried the following-
-checked timing belt.
-replaced cam position sensor
-replaced the ocv solenoids
-removed the 2 easily accessible avcs filters.
-changed the oil( 10w-30)

The only thing that has changed since replacing these parts is that now when the car comes to idle and starts to die the oil light flickers on, it didn't do this before.

I have a new stage one block from P&L with all new turbo,intercooler, oil & water pumps with 5000 miles on it with a conservative tune, so I don't think that it should be having a oiling issue. I was just at P&L last Friday for a tune for a EWG and did a PDI, so there are no leaks. I was however about 1 quart low on oil with 1500 miles since the previous oil change. ( only put in 4.5 qts to start with)

The accessory belts are cracked and old and I can hear them squeeling when the car starts to die, so I don't know if replacing them will help anything?
Any other suggestions to try before I have it towed back down to P&L?

Input your vehicle info for more help....
And with all the other items you have done check into the "oil pickup tube failure" threads.
Sounds like a bad/cracked PU tube however we need to know what ya drive!
