Power Stroke Diesel, about a week ago, first I noticed strange things going on, like my ADS light came on, then the Overdrive was flashing Off. Then my speedometer went crazy, one day I was slowing down to stop when I got to about 30-35 mph it would just drop to 0. I've been working long hours, and had not had time to check into this. Then today, it seems that it has just decided die if I go over 40 mph. It will start back up, but will die again if I get to 40 mph. I've checked and noticed to that my trailer lights don't work either. Does anyone have any ideas where to start?

The same thing was happening with my speedo and i changed the VSS, but it's still doing the same thing, once it hits 30, it drops to 0. What could be the problem.

It didn't fix everything!!
Well I took the truck out today, and apparently all is not fixed yet. Everything is working properly as for the other problems, but now it just dies for no reason. Does not matter what speed now. I may go 10 miles or may go 2 miles, then it just dies. I can start it up ok most of the time, and it may run for a while, and it may not. Other times I have to wait a little bit. Now, I thought I would move on to the next advice, changing the VSS. Where it this located? My ABS was located on top of the pumpkin, I can't find any VSS there? Also is there any chance that the CPS is going out again? I have only replaced it once a few years back.

Not according to Napa.Go in there and ask for a vss and they will hand you something that goes on your tranny.Its got a mechanical con.(spedo cable maybe not sure) and an electrical connector (3 prong if i remember).

Well it seems I've come full circle. As I said in the first post that I had changed the CPS a few years ago as the board suggested would fix my problem. And today I had to change it again, and fixed the last of the strange set of problems that had been occuring over the last week. Thanks to everyone for their help.
