Weird Voltage Cut at WOT

[Brad2jz]

Need someone to help me diagnose a problem i am having with my ECU. It started out from a random cut to doing it all the time now it only happens at wide open throttle and getting it into boost. On the log it showed that the ECU and sensors all fell to 0 volts and I'm have tried 2 different M800's in my Supra so i know its not the ECU itself. Any Help would be greatly appreciated.

Thanks,
Brad

The first place that I would start to investigate is your grounds, make sure that they are all done up tightly, and that they have no build up underneath them that can cause a loss of conductivity.
