I have a 1994 Lumana APV w/3.8 Litre. Intermitant problem where it dies while driving after 14 miles. Acts as if it is running out of fuel. Has new fuel pump, crank and cam sensor and PCM. Fuel pressure is steady @ 32 lbs and increase to 40+ with the regulator unplugged, but does drop to 10 lbs at times. Would the next logical step be the regulator? No codes stored.

Hi, my info says 40--47 psi key on, engine off. Idle 30--44 psi. Any electrical part, if there is a problem with the electrical harness, replacing the part won't fix it.
