I have an RC3020-30 that will go forward and reverse but then randomly go out either direction and do the PMT before completely dropping out where you have to turn the key off and back on. Sometimes after turning the key off and then back on it will fix it and other times it won't. After sitting for the weekend not running at all, it was dead in the water this morning again. Finally after turning it off and on several times I was able to get it going. I changed out the third snubber from left and it started working for half a shift but then it is back to doing the same problem. Any advice would be greatly appreciated.
