Hey there folks! It has been a long summer (too short if you live in Michigan!) The reason for the original post was twofold. The first being that the truck motor would cut off and turn back on while driving with no notice. The second reason was for the "rough running" symptoms that I was experiencing. I did a lot reading/researching in most all of the Ranger Forums and there are many, many posts just like mine. The problem was that I did not come across any with any solutions. Like I stated in one of my earlier posts, all of my major sensors checked out OK. I researched our ignition firing system (EDIS6) and checked the components. This is what I found at my Crank Sensor:

I thought that this may have been the cause of my problems, especially with the motor intermittently cutting out. So, I taped the wires carefully and plugged it back in (I will be changing the plug this fall sometime). The truck drove great for a couple of weeks. Great, its fixed!! Then I drove the truck to my sister's in KZoo and (2) miles from her house and the truck cuts out!! I got it to limp there and then later in the evening I had to drive it the 2 1/2 hours back to "Metro Shores". The truck wouldn't drive over 68 mph and I had to leave the CC on to get home. If I had to come off the CC the truck would die. That was a fun drive home!! Not. Anyways, more reading/researching and I found this video:

So I figured what the heck do I have to lose? I pulled my PCM and sure enough, just like the video, one of my capacitors had leaked out. I replaced the (3) capacitors per the video for a whopping $5.00 (highway robbery actually, since they are less than a buck a piece on line). Re-installed the PCM and the truck has been running great ever since!! So, I hope this helps someone out with an actual answer to their "rough running" Ranger problem.
