So, as you've probably seen from my posts, my car gets to the track a lot. About a month ago fuel cuts started happening in hot weather at higher boost settings, now the cuts have gradually worked their way into stock mode, so there's nowhere left to go other than to fix it. Under just mild load now the car will act like the accelerator cable got cut (yes I know there is none), engine loses all power, then I let off gas, then it comes back. Its not a violent buck, it just loses all power.
The low pressure fuel sensor has already been upgraded to newest part (06E906051K), cam follower is fine (just checked it). The high pressure pump is the factory unit, I don't think they tend to fail outright, but I'm starting to believe the low pressure unit in the tank is failing, and it seems to have all the symptoms this article lists:

Anyone else have this fail? Seem like reasonable part to replace before I spend the dough?
