I wasn't really sure where to post this, but here it is...

91 Tsi 5spd, pretty much stock as far as fueling except for a re-wire, lc-2 wb.
I was on my way to work last week and took a turn onto the highway, mid turn I went to give it gas in 2nd and the car bucked twice like I hit fuel cut but then seemed fine...It was running great before that, was hitting around 11.5 afr on steady 14lbs. Now since then when I go into boost it stays around 14.7 no matter what. It runs great otherwise, idles and pulls fine, even under boost it still runs like nothing happened except for a slight power loss. No fuel leaks, all new sensors, I swapped the ecu with no change. Any ideas? fuel pump or fpr dying?

Also forgot to mention that since then it takes forever to start, it used to start right up no problem, like it isn't getting fuel. The fuel solenoid has been removed since I bought the car, and my boost gage is T'd into the fpr line so I know its seeing boost.
