#1The boost pressure sender won't cause poor running, and won't cause fuel cutoff.
#2Fuel cutoff is quite obvious and dramatic engine shutdown. Fuel starvation would be a separate issue, but I doubt that's your issue.
#3Not sure what that other doohicky sender next to the boost pressure sender is. Picture would help.

My guess....check for an air leak in all the plumbing downstream from the turbo. If you're loosing boosted air, you'll get progressively richer and could cause the stumble/lack of power. Could be other stuff like a bad vacuum connection somewhere, or ignition timing dropping off.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
