well, after spooin feeding information to my buddies shop tec, they have finally given up so I am here working on it. Impedance values for the injectors is ??? how many ohms?  will continue to look around here and see If I can fnid it, but if anyone know of the top of their head yell them out loud.

I am looking for the 727 computer, 128/ 260 versions as a possible failure point, wouldnt be too suprised if the injectors were bad, dealer replaced them a year or two ago and the car ran just fine in that time until I went mach 2 on the highway that night...

Havent ruled out bad gas, but it seems to be it will run and start drive a bit then die, wont start for a few hours, start eight back up and do it all over again. Water enriched gas I would think wouldnt allow for the car to restart... I am leangin towards the drivers getting too hot in the ecu, for what ever reason. impedance out of spec on the injectors, bad ecu driver assembly.

Blah Blah Blah.... Sorry guys.

11-12 OHMS per injector... 8)

It sounds like your crank sensor to tell you the truth.  I had a Dodge Dynasty that did the same exact thing your talking about.  It would run for a while quit and not start right away again.  Go out a few hours later and it starts right up.  I replaced the crank sensor and it never did it again.

Crank sensor or Dis module...

The first thing I would do if I were you is to find out whether there is fuel and spark when you have a stall/no start situation.  If it's not getting spark then I would check the DIS module first as it's easier to replace.  Then I would move onto the crank sensor.  If it seems to be a heat related stall as in it starts to warm up, stalls and then won't restart until it's cooled then I would put money on the crank sensor being bad as I had the exact same thing happen to a Olds Ciera (3300 not 3.1).  It would start and run great for a couple miles then it would stall and not restart until I waited a while for it to cool down.  I replace the crank sensor(located on the dampener on that engine) and the problem never came back.  Good Luck :)
