Default Have no clue what happened, now engine wont start

Was tuning my 454 lsx LS7 top end setup on E85. Everything has been going well for tuning today, then all of a sudden at the end of this log file that is attached the car died... The car was at WOT then after the WOT pull it all of a sudden died and had pull to off the road.

At the moment that happened you can see that it went to 2.63g/cyl airmass and injector pulse shot up to 33ms, AF was at 14.75:1 at the instant.

Have never seen this before and the car will not start at all now.

Has anybody else ever had this problem?

please help.

Thanks

Whip out your fuel pressure gauge and verify you get ~58psi at the rail when you turn the key to RUN during the 2-sec prime.
