2011 Tiguan Start / Stall when Hot
Vehicle: 2011 Tiguan 2.0 TSI
Problem: After driving the vehicle and letting rest for 20-40 mins, the vehicle starts/runs/drives for 30 seconds to a minute. At that point the engine stalls. It sometimes will start again right away, and sometimes it can take a half hour to get it going again.
Troubleshooting: With a scan tool plugged in, when the ignition is first turned on, the fuel rail pressure is between 1500 and 2200 psi. When the vehicle is started, the fuel pressure sits around 550 psi at an idle. After 30 seconds to a minute, the fuel pressure drops to between 68 and 80 and the vehicle stalls. The fuel pressure remains at the 68-80 while trying to start. When it eventually starts, it levels back off at 500+psi. I unfortunately haven't tested what all these numbers look like on a cold engine, but I never have a problem with a cold engine.
Parts replaced so far:
1. Fuel pump driver module (green box under rear seat)
2. Coolant Temp Sensor on the lower radiator hose
3. High pressure fuel pump
4. Camshaft follower for the high pressure fuel pump.
Being that I retain the 60-80 psi, I don't believe that it is the low pressure fuel pump. What I find odd is that the high pressure fuel pump works when it is first started (can hear the clicking), but then just stops. Anyone have any insight into what may be going on?
And for the first time ever, just now as I was typing this, the car was sitting at an idle for about 20 mins and stalled. I don't have my scan tool with me so I'm not sure what is happening at this exact moment.

First posts normally go in introductions else you could get a free fix and we never see you again!!!

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

As I've said:

EOBD II Error Code: P2294
Fault Location:
Fuel Pressure Regulator Valve (N276) - Open Circuit/No Signal/Communication
Possible Cause:
Malfunction Indicator Lamp (MIL)(K83) active.
Fuse(s).
Wiring/Connector(s).
Fuel Pressure Regulator Valve (N276) defective.
Possible Solutions:
Check/Replace Fuse(s).
Check/Replace all faulty Wiring/Connector(s).
Read Measuring Value Blocks (MVB).
Check/Replace Pressure Regulator Valve (N276).
Special Notes:
On some engines, the Fuel Pressure Regulator Valve (N276) may be referred to as the Fuel Metering Valve (N290) in the factory wiring diagram.
