My truck will run fine until 30 to 35 mph then all systems die! Just like I shut off the switch. Transmission has a problem with reverse but otherwise is fine and will shift. I have replaced the sensers that the flash codes say are faulty, what next?

Puzzling one indeed. Curious what sensors did you replace and codes that pop'ed up. Seems to me like seems pretty obvious do to with the electrical. Did it have this problem before the sensors were replaced or replaced due to the problem. Im asking alot of question and not offering much help hopefully we can get some were here

Engine coolant temp sensor, code and replace, vehicle speed sensor, code and replace. This may help, reverse is not working, tries to catch but will not move could it be a sensor inside the tranny?
