hello, Im experiencing a brake-up at only MID-Throttle points,after 15 min of driving.

My A/F goes lean during the brake-up,all my plugs are white...

what could possable be the problem, i already switched 2 MAF's and set the timing and rewired/checked most the the harness. swaped an ignitor and coils...

WOT feels good (11.9/ 12.0)... but its like anything other then that is Pure lean... except like 10% throttle. but its only after 15min of driving... it almost feels like the hotter it gets the worse the brake-up becomes...

this is really starting to tick me off.. i have lost much sleep over the weekend, plz z for the love of god... if anyone has any experience like this, help
