My van likes to shut down on the highway and at green lights. I've changed the starter, alternator, battery, IAC, tps, sp/ws/dcar/ff/af, and had to mess with the timing because the distributor was loose. I can't read the codes because my data link connector won't give them. After changing the rotor, it started up, no problem. Next day, back to square one. Changed the fuel pump. Started up just fine. Turn it off to try again, back to square one. What is the problem here? I've tested the ignition control module off the van, and it always passes. I need help.
