Motor bogging down

Have a mark v 1 1/8 hp motor. I trued it up 90 degrees to table. Blade is parallel to fence and miter. Cut a 2x4 for a test cut and it bogged down. I pushed it slower and it seemed better and no burning. I am wondering if a belt is slipping causing it to slow down? Anyone have this problem? I tried it on 3/4 plywood and still not good. Any ideas please let me know.
Thanks,
Tom

What speed did you have the speed control set to?

What tooth count blade are you using, and is it sharp? If you are ripping with a trim blade that can bog down the motor.

Is the blade also clean?

Are you attempting a 1 1/2" or a 3 1/2" deep cut?

Counter-intuitively, when the saw bogs down, slow the speed control down in order to gain greater torque. Slow your feed rate as well to account for lower saw speed.
Assuming you have already eliminated the table and fence alignment issues (which are the usual culprits), the possibilities in no particular order are:
Dirty, damaged, or dull saw blade.
Saw blade on backwards (I've done it with a outside chipper on a stacked dado).
Arbor nut not properly tightened on blade.
Arbor not properly attached to quill (either not aligned on the flat area or set screw not adequately tightened).
Using the wrong kind of saw blade (a cross cut blade being used for ripping).
Mis-aligned upper saw guard/riving knife.
Failure to use upper saw guard/riving knife and cut closing/pinching blade.
Loose belts.

I am wondering if I over looked the problem? It is on a long long extension cord and also had the dc3300 vac on at the same time? Drawing to much amps to maintain the power to operate at full capacity.
Thanks,
Tom

That's another possibility. Although I would have assumed you would have popped the breaker or blown the fuse.

Fer sure! If it is long enough, the current will be limited by the cord resistance and prevent tripping the breaker.
I am guessing the wire size is small as well.(#16???)
