Sudden power loss

Update... I'm still having this damn problem. My car sounds like it's going to bog down and clunk out but has only shut off once like that. Other times the traction control light comes on and goes into limp mode. Of course this never happens when it's at r/t tuning which is who tuned me and they said unless it replicates while it's with them it's impossible for them to figure it out. I know it has something to do with the throttle bodies or tps but I can't have Nissan do a relearn because of my custom tune and when r/t tuning had me do a manual relearn it just seemed to make it worse. I'm getting really tired of this issue. Also now my wide band is staying at either 10 or 20 so I'm guessing my idle air control valve in conjunction with the tps or maf sensor location is the culprit but I'm stuck because r/t tuning is 4 hours away from me and they said only Nissan can do the relearn so I guess I would have to drive it up there have r/t remove the tune then tow it to the closest Nissan dealership up there so they can do the relearn procedure then tow it back to r/t for another tune.... Ahhhhhhhhh
