Will start, run for 10 - 20 sec. then die. I can eventually get it to run after about 5 - 8 attempts. If i drive it i have had it die on me several times in the middle of the road or at a stop light so now it's garaged. I've replace the fuel filter. Fuel pump is a few years old, maybe 30 K on it. Have tested ignition module Ok. Inspected cap, rotor,wires, connections etc... No OBD codes. Now I'm lost?

Have you checked the fuel pump pressure at the engine pressure port?
