I take that you are out of the 3/36 basic warranty.
Your scanner probably only would show engine (PCM/TCM) codes, but are there any SKIM (WIN) or TIPM fault codes? The dealer scan tool would be able to read the other modules.
A failing fuel pump wouldn't really explain the cluster gauges all dropping out at stall-time. The warning lights would come on and the tach would drop out at stall. That sounds like an ignition (+) power or communications bus problem to me.
If you play with the ignition switch by moving the key slightly towards 'off' and 'start' and tilt the column up/down slightly, does it bring the electricals back to life? Some PTs had ign switch and column-to-dash wiring harness 'rub-through' issues. I don't know if this changed by 2009.
A fuel pressure gauge attached to the fuel rail with a 4' hose could reach and be pinned under a wiper blade (if it isn't raining) to watch for fuel pump pressure drop out before the stall. Again that doesn't explain the cluster behavior. I think that there is an ignition (+) electrical feed failing somewhere. There may or may not be fault codes for this. The Co-pilot data recorder is a useful tool for this kind of diagnosis.
