Default help with turbo problems?

Hopefully someone can help me diagnose a problem that has been happening recently. I have an 05 s2000 with just the greddy kit and bov, i have new plugs and new coil packs. One of the major problems is at any random moment in no specific revs or speed the car will completely lose power. The gas pedal doesnt do a thing and i hear a kind of low dense rattling sound. I usually coast to a stop and the shuts down as soon as im not moving and i get a oil pressure light and the battery light. This happens randomly and its kind of scary. I know its not low oil as i have checked the oil levels and it seems fine. I went ahead and ordered a new oil pressure sensor but im not even sure if thats it. Anyone have any ideas?

Go and get it tuned. There has to be some specifics. a certain rpm range, throttle position....

Actually i did get it tuned, i think the problem is independant of the tune though, on basemap i still get this problem. I know its not my emanage or harness either, i sent it to greddy to check and its fine. Any other ideas?

i believe its electrical...oil pressure light and battery light...this happened to me on my civic not constantly though and i had a short that eventually blew a fuse causing everything mechanical to go dead...my fuse happened to be the fuel pump by the way...the wrapping on my fuel cut off wire had come loose and contacted the chassis...goodluck diagnosing it...u dont get a cel?

when everything goes dead do all the electronics work? when the car shuts off does it stumble or does it just cut off? if your not getting a cel im kinda ruling out anything mechanical...how long does it take for the car to start back up or how do you start it back up? is it a simple as just pushing the button?
