pull the trigger, current flows, heat builds, the connection is lost. sit a second, cool, connection regained. lather, rinse, repeat

That's very possible.

I'm wondering if it does this when driving slow also?

Those Bursts do really spike the amperage.

The problems make me think they are dean's connectors. Correct?

Although they may look good connectors go bad from the slight arc of connecting and disconnecting.

I had the same problem, new connectors solved it.

please try and report results(I'd like to know if I diagnosed it correctly, I learn from my mistakes!)
I may have to switch everything I have over to Traxxas or Losi EC5 connectors. Those don't spark very much if at all when you plug them in right? My Deans give off a fireworks show when I plug them in.....

If you left some wire attached where the switch used to be, I would see if those wires are good all the way to the board. Maybe there is a loose connection at the board for the switch wires.

Hmmmmmmmm..........
I eliminated he on/off switch but there is still like 2 inches or so of wire left. I will have to have a look at the board and see if the connection is loose. But what makes me think it can not be a loose connection is that I can take the wheels off and rev it like that so there is almost no vibration and it will still do that.

Do you mean where I soldered the 2 wires together when I removed the on/off switch? I did this even before that so it seems like it couldn't be that, but I will have a look at it and try that.

It mainly only does this at low speeds. The first run when I had a large open area to run it and I could keep it from 2/3 throttle to full throttle it wouldn't do it, but when I would let it go below 2/3 throttle, if I let off any it would shut off, then turn on, and would keep doing that until I got it back up to speed again.
