Fished two day tourney this weekend, and ultrex was flawless as usual. Rained heavy overnight, boat sat outside since we were on a trip. Everything worked fine for about two hours Sunday and then the pedal got real firm going left, like I'd lost my power assist. It functions perfectly to the right but not left. I fought with it for a while like that until it finally locked up. Power off then back on helped a few times but that eventually stopped working. After googling on the water what it could be, I tried using my remote and as soon as it came on and paired the motor went straight to the right and locked up. After that it took a while even with the remote off to free it up and get it to move again at all. Spot lock would try to engage but immediately disengage. Realizing I couldn't do much about it at the time being and it costing me quite a bit of time and aggravation, I may have gotten a little mad and stomped the foot pedal. Low and behold my steering came back, power assist and all. The problem came back and was remedied the same way a few more times before I power poled down for lunch. Scanned a while, and fought it again before it sporadically worked again, even spot lock, toward the end of the day. The problem seems relatable to a few different things except for the fact that it's intermittent. Voltage and connections are good. Any other ideas?
