The p008B code that you listed refers to the low pressure fuel system. For some reason the engine control module is receiving a signal that shows high pressure in the system. This could be caused by a failed low pressure fuel system sensor, a bad/corroded connection, a wiring problem, a faulty fuel pump driver, or even a blockage in a fuel line. This particular code is one that is only a starting point for diagnosis and will require further diagnostic testing to identify. When it comes to a situation where a vehicle stalls, this can be caused by a clogged fuel filter, faulty fuel pump, a vacuum leak, or even a failed sensor. It sounds like the two issues you listed may very well be related, but not necessarily. If you need some help further identifying/repairing the problem, contact a certified mechanic, like the mobile mechanics at YourMechanic.com.
