Electrical issue with trailer connected
I have what appears to be a unique situation with my 2012 Shadow Cruiser. With several different tow vehicles now, I am getting some sort of electrical feedback that is causing problems with the engi...

Have you added LED lights recently - Some of the LED BOARDS that have REGULATOR CHIPS on them will create alot of RFI SIGNALS that could possibly be getting into your truck's computer system???
It would seem to be a very unique electrical reason however to be back-feeding something back into the truck 12VDC system by just connecting up the 7-way trailer connector plug.
Almost have to fall back on something you may have added - maybe a large 4AWG battery cable to get the trailer batteries to charge better when connected to the truck system...
If this has just started to do this you need to think back to something new you may have perhaps done to the travel trailer???
The only thing the trailer connector does is provide 12VDC power for the trailer outside safety lights and electric brakes. It also sends a 12VDC charge connection to your trailer battery. These are the only OEM connections between your truck and trailer which makes it hard to imagine something is getting fed back into the truck computer system to change the parameters to your truck's performance package...
I would rule out something I have recently done first... My truck's 7-way connection is all protected by separate 12VDC fuses on each safety lights functions. Perhaps you can disable each leg one at a time feeding the trailer and see if you can pin-point which leg is getting the feed back into the computer system.
You sort have to rule out your trailer on-board converter/charger system having bad 12VDC regulation since it not 'ON' when being towed.
High wattage INVERTERs also put out alot of RFI signals if you perhaps have one of those running when being towed... Maybe powering up a fridge when being towed...
