Bob,

First thing I would check are the brushes. If they are worn or making intermittent contact, that might be the cause.

Does the problem happen at all speed settings? It could also be a bad speed control board. I don't know what model saw that is or how old it is, so I don't know how it regulates the motor speed. I'll see if I can find anything else obviouse.

Welcome to the forum,

searching 601 and not 610 was the trick..... You saw looks like the older version of my Q3

Your unit has a speed sensor in the base. If the gap is packed with sawdust, or the sensor has come loose and the gap has changed, the saw may not be able to get the feedback it needs to regulate speed.

If the components are bad... It ain't gonna be a cheap fix.....
