Electrical issue. Anyone have similar problem?

[Jmb75]

I have a 2012 Raptor and about 4 months ago I go out to my truck and I have no power at all, no auxiliary power nothing. I disconnect the battery and reconnect after couple of minutes and everything works fine. Took it to the dealer they can't find anything. Since then I've had my front power windows work but rear ones worked fine. Last issue was this past week. Got into truck after work was pulling out of work and the truck stalled twice. When I got upto the next couple of red lights I'd watch my RPMs bounce up and down. Every time I've had a problem it had been raining also. Took it to dealer again and once again they don't know what's going on. Has anyone had any similar issues? Any help would be greatly appreciated!

Any mods with exposed wiring? Something is messing with your ecu.

You can really only troubleshoot when the problem occurs. I would start with metering everything possible. See if anything is shorting out.

Is sounds as if the system ground is floating. Below are things to check.

1. Check the ground cable on the block.
2. Check to see if the alternator bolts are loose. The case of the alternator becomes the ground when the vehicle is running.
3. The battery may be trash and causing a electrical loop to ground from the positive side. This may have caused the power outage.

I too agree with ground issue IF no mods/aftermarket parts have been installed.
