I had a similar experience with an old rotary of mine. It turned out to be the power cord which had developed a break in the wire near the strain relief where the cord exits the machine. It would cut-out intermittently as the orientation of the machine changed.
It's an easy diagnosis and fix... simply get the machine running and the wiggle the cord. If it cuts in-and-out while manipulating the cord then that's the problem.
All you need to do for the repair is simply cut the cord to remove the offending section and reattach. Or get a new cord if the existing one is getting too short for your liking.

And the repair could not be more simple.
It is no coincidence that man's best friend cannot talk.

Re: Flex 3401 stopped working
I want to thank you guys for the feedback to my questions and comments.
I was able to verify the power cord to be the culprit.
I placed the order today for a new one.
This machines are easy to work on, I was able to replace the brushes with ease and slapped it back together with no problem.

Just had this exact problem with one of my 3401 polishers. Cut off a foot of cord, reattached, worked great! Went ahead and ordered a 25 foot replacement instead of the stock 15 foot. Much better!

As I said, I’ve ordered a new cable. They do say is an upgraded cable. Hopefully is a longer one.
Question, though.
Did the cable you’ve ordered come with crimped end connectors?!

Yes, it had the crimped ends like the factory cord. I ordered mine from the flex parts supplier mentioned earlier in this thread. It was about $60 shipped. The next day, my local P&S supplier came through to deliver some supplies. He carries a 15 foot cord identical (same markings even)to the original flex cord for under $20. Now I know. Lol.

Just an update.
Tonight I've replaced the power cord, and the machine is up and working strong!
Huge thanks again everyone!
On another issue...
I have another flex 3401 that is completely dead.
After replacing the cable and the brushes, still a no go.
This is my back-up Flex 3401. I have two, and this is the first one I've ever bought about 12 years ago.
I'm temped in ordering the switch, or perhaps send it over for repair.

Glad it's up and running again. Mine is going strong and about to get a workout on a nice Jag today. My plans are to add another Flex to my cabinet early next year but I'm waiting to see if there's a new and updated version coming out. Even then, I'm actually a little hesitant on that just given the current model has been so reliable.

I think there's a new version coming out shortly with a plastic shroud instead of metal, and handle like the 15 orbital.

Hmmm......life has too much plastic in it already. I'll take the weight and quality vs plastic. May have to stick to what I know works well.
