    I was headed to Crusin the Coast. Car was running great. I've been driving it a lot. Thought it was ready to go. About 50 miles from home, I was running about 60mph, it died just like I turned the key off. Can't figure it out. will not fire. Cranks over. This thing is killing me.

    Cranks but won't start. ( 9 times out of 10 it's ignition.) Check for spark while cranking first.

        That's not dead.
        It's just testing you.

                How old is your timing chain? Did you check to see if the rotor turns when you crank it?

                  Had same sudden failure once, a long time ago. Ballast resistor had burned open. A little piece of a hose clamp between those female terminals bypassed the resistor for the to drive to the part store.
                  No resistor for long term could overheat / damage the coil.

                    This is why I eliminate the damned ballast on every Mopar I own.

                    I actually just relocated the ballast resistor from the ignition system to my wiper motor (it was only working on hi speed, and this solved the issue)

                      Title is a little misleading.lol i opened this expecting to see rods hanging out the bottom of a block...not a minor ignition issue that can probably be fixed for somewhere in the $12-$80 range :p

                        Did we ever figure out if it was ignition? I always check for fuel first. No tools required for that.

                            Mine did the EXACT thing Monday afternoon...
                            Steps...
                            1 ballast resistor (kept spare in glove box)
                            no start
                            2 ECU (kept spare in glove box)
                            no start
                            3 coil (spare kept in basement DOH!)
                            no start
                            3.1 put hi-voltage spark plug wire back on after forgetting DOH!
                            START! YAY!

                            I can remember back in 1971, I believe, having this same problem with a 69 R/T, 440 six pack. Ran great for two years, then I cleaned the engine on one bright sunny day. All of a sudden it ran very rough, or rougher than usual. Then it stopped. Can you believe that I had it into a Dodge dealer in the Quad Cities, couldn't find the problem, then to a local garage who thought that he had it fixed, just to find out not. Several starters, battery, plug wires, coil, the only thing that I missed was that ballast resister. Finally sold it, AS IS to a guy returning from Viet Nam. That was the last that I saw of it until about six years later when I came up behind it on the street. Could always recognize that R/T with its Dana so visible from the rear. Ballast resistor was what he changed, first thing, and it ran like a top. Expensive stupid lesson.

                            That's my thoughts, exactly. Biggest mess-up that Mopar ever did, well maybe one of them. Killing the A-Body Barracuda was another.
