Yes, the house breaker.  I don't have a festool vac, using a shop vac.  When I sent it back for service they replaced a bunch of parts.   The saw itself is drawing 13 amps continuously, and then the amps spike and the breaker blows.
Sounds like you have a few coils that are shorted in your armature.  This can happen when it is wound and the insulation on the winding coils is not complete.  Does it fluctuate in speed under no load?  Is the motor housing getting warmer to the touch?  If you have someone with a PAT tester, ask them to check the tool for you.

If it is drawing 13 amps continuously, it has to be generating a lot of heat.

Thanks for the info.  Dovetail65, does your saw draw the 5 amps while cutting?

Hold on let me make a cut.

Okay I just cut a 3/4" piece of ply and the Makita went to 11.75  amps, but the saw didn't make any kind of sound that indicated it was pulling any kind of additional power and it cut through almost like cutting air.

If I didn't have a meter on it I would have guessed the way the saw acted that it was pulling maybe an additional 1/2 amp(over the 5+ amps it pulls with no load), so the 11.75 was surprising.  It must be something to do with  the circuitry keeping the saw so smooth and silent while puling more current.

I'll have to pull out some hardwood to test better. My brothers TS 55 isn't here today so that will have to wait. Ill be cutting some Wenge and Ipe later tonight, Ill post up  the current draw on that for the Makita. I also have some wet 2x6 Green treated, that might stress the saw a bit, Ill test that too.

I just tested  the Makita full depth in a 3" slab of SIPO(of course it cant cut through that) the meter read a bit over 16 amps flickering back to 15 amps.

The one who says it can't be done should avoid interrupting the person doing it.

He did say that the breaker was popping. So it must be >5A.

Update.  Just got my saw back from Repair.  Replaced the electronic module.  Hope this does the trick.  Thanks.
