PROBLEM SOLVED!!! BAD VEHICLE SYSTEM GROUND. That's right I said it. Working with a brand new 2024 Honda Pioneer 700-4 Forest (so you know that comes with the warn 4500 winch) I began having problems with my engine shutting off. This began after I got my home made roof, light bar and cab lights all installed. But one more thing to add was vertical channel iron to the front bumper and horizontal channel iron over the roll bars which I installed roller fairleads for winching backwards or pulling a big deer into the bed. Hey, I'm well past 60 so I look for ways to make my life easier. Back to the winch... so every time I was turning on the winch, it didn't matter forward or backwards it would cut the engine off. Contemplating taking it back to the dealer wasn't an option for me because I live in middle Georgia and I drove to Jackson Tennessee to buy this one, (a fourteen hour round trip) but worth it. So, after reading all the wonderful comments here and in Honda forums I was about ready to go for the second battery installation option. I have my own shop and decided to troubleshoot myself. I had a pair of jumper cables so I got my boat battery out and set it up on a stool in front in my shop. With the positive power cable disconnected from the winch solenoid and using the jumper cables from the boat battery I surprised that I was getting the same result still. So why not jump the negative (ground) side and see what happens? Without even using the spare battery, I used my jumper cables to jump from the Pioneer battery negative to another clean ground point under the seat. BINGO!!! We have winch turning and Pioneer still running without so much as a sniffle. Well the obvious at this point is to remove the jumper cables and check my vehicles grounding points. I didn't look real deep but I did find two right off. One grounding the front of the engine and one grounding the frame up near and under the fuse box. They were both factory tight as well as the battery terminal itself. And I'm still having the same problem unless I have jumper cables assisting the ground sequence. Seeing where I need to go now... I just so happened to have a spare # 6 black cable with eyes already crimped on each end in my box of old winch parts. Snugged it down to the negative battery post and attached the other end to where the oil spout attaches to the frame under the drivers seat. Wala, I have had no more problems after adding this extra grounding cable. I cannot explain why the factory cables are not enough to do the job but forget about extra batteries and the Dual Battery Connect & Monitor Kit which together might cost you $3-$400. Hope this helps the next fella.
