There a number of things that can set that code off.
Excessive fuel Return to the tank
An empty fuel tank
Fuel injection pump failure
Fuel pressure regulator failure
A restricted Fuel Filter.
If you have to prime the fuel system, check for the following conditions:
A restricted fuel supply line
A fuel supply line air leak.
Have you changed your fuel filter since this has started happening?

I've had one plug up at 8K because we were getting some bad fuel in the area for awhile. Change the filter and lets go from there.
