Powercable problem to measure , carbonbrushes remove and watch if no autostop protection (a little black pin comes out the front of the brush you must remove to see this if its happend ) so yes replace the brush do not remove the pin .
or a contact to the switch or one of 4 points of the electricfield is defect measure both fieldcoils measure between the form carbon brush to carbonbrush through the anchor for an broken collector you see sometimes visible damage of the collectors on it if one stands on a brush it will not start and if it starts by a litle turn by hand of the air-vin of the anchor it may uses or a humming noise and hot or draws sparks and become in any case a hot machine drawing too much power

your missing a tooth on a large round gear in the gearbox.
when the gear on the engine rotates into the position where the little engine gear spins because there is no tooth to come into contact with the engine runs but the gearbox doesnt spin, hence no reciprocation, but engine runs.
if you bump the blade it will start going again, but when you cut it will stop offasionally in mid cut. you can repair this but stop using it the engine gear will be destroyed otherwise
I have a dewalt dw303 that you can use for parts, I need a new trigger or something the motor is dead and I found a new saw. go to craigslist.org, rochester ny tools section and look for dewalt dw303 that is my listing. for ten bucks ill sell you all the gears you need. i think it is close to the same model, i am sure it is the same gearbox.
try opening your gearbox, im positive that is what is wrong.

Before you attempt any of this I would recommend going to Dewaltservicenet.com and see what the inside of this tool looks like. It appears that you need to remove part of the front gearcase to get into the lube. The back e.g. brushes is not that big of a deal. If there is a Service Center near you they have a Max repair rate that they will fix anything on this saw at a preset firm price and if it is less that is what they would charge.

SOURCE: Blade won't lock.
There is a ball lock in it and you have to twist the ball lock but if the ball lock is frozen generally WD40 will help unfreeze it and work it until the ball is free and should work just fine.

Point tool away from body.
2. Rotate blade clamp collar (the knurled diamond pattern knob just at the back of where the blade goes) to release position.
3. Insert blade shank from the front.
4. Rotate blade clamp collar to lock blade into position.
