Sounds like you may also have problems with torquing the blade, so you’re getting plywood in contact with the side of the blade rather than just the teeth.

It’s not a function of saw power, it’s a function of the blade generating heat, and how it’s dissipating heat. So either the blade isn’t big enough and you’re not radiating enough energy (which is possible, but I doubt it if you’re having that problem in a foot of cutting), or there’s something in your technique with the blade that’s causing the side of the blade to rub on the wood, heating far more than the teeth of the blade would.

I had similar problems with a low-end saw whenever I tried to cut along a straight-edge. I now have a Festool TS55 circular saw that runs on a rail, and have had no problems with blade alignment relative to the guide, and can rip two-by wet fir with no problems.
