BS3 car dropping passenger side bank
I posted in the tuning section with no replies so I figured I'd try here. My car is at the tuners and it will drop the whole passenger side bank for no reason at all. They're thinking cam or crank sensor. Any ideas here? Car is a 408, 4l80E, BS3, S91 car.

I would Imagine it is in the crank sensor. I would start there.
Is it shutting down spark or fuel, Both?
Is it while its under WOT or part throttle is it Intermittent?

From what I was told the tuner was working on the car. Had it idling and running smooth and all of a sudden the passenger side dropped out. The car is now back in my possession and I may try to mess with it some. They tried a crank sensor but it didn't help. I'm going to check the grounds, fuses and wiring. I don't think it should be that tough to track down with BS3. I'm using moroso 10.4mm wires with a relocation kit.

This is just an under the cowl extension setup with no extra harness. I do plan to check all the wiring associated with that side though. EDIT...I just played with the car some and for some reason my fuel pressure was only at 44psi. I turned it up to 60 and it almost starts now. Why would the tuner have turned that down? It was at 60 when I took it there.
