One of the engines would randomly stop running at idle. Changed the IAC and foam filter. No difference. Today I put a pressure gauge on the fuel rail, and here is what I observe: At startup, the pressure is steady at about 30 psi. Engine sounds fine. After a few minutes, the pressure suddenly starts to flutter. Then it flutters down to zero over about 2 minutes and the engine dies.
Is the next step to take apart the cool fuel module, or just look at the pressure regulator? What else should I be looking at?
Previous owner already changed out the cool fuel module. I changed the fuel filters last month.
