running a stock d17a1 with rdx injectors, motorola 2.5bar map sensor, and kpro. engine cuts out at high rpm/load. i have to let engine speed reach zero and then restart by cycling key. have read of other people having same problem. datalogging it is difficult for me because my laptop has no battery and i use an inverter to power it, so when i replicate the problem, i forget to save the log before i cycle the key and therefore lose my log. have read other posts of same thing occuring at a few other forums.

conditions i've noticed while problem occurs:
tps above 50%
load above 5psi boost
rpm above 4500

i find that it occurs more consistently when i snap throttle while in mid range rpms. TPS is verified good throughout range of movement

Without a datalog and the calibration it is impossible to say what it could be.
