Could be a leak in the system and sucking air. Check the fuel filter, make sure its tight. Check the filter housing, lines, etc. You can press the primer bulb a couple of times and see if it hold prime or a leak downstream shows up. The primer bulb should be firm when working properly.
If all that checks out fine, very well could be a failed CP4.

When was the last fuel filter change? could have some stuff plugging it up causing a restriction. Are you in cold weather climate?
