Motors shaking after couple minutes of acceleration, short?

Ok, so ive been tearing apart my board all day looking for a short. i found some things that i thought could have been the problem but it didn’t fix it. i cant find a short anywhere. What else should i look into. Every time i take it out it works perfect for the first little bit then starts to shutter? any ideas?

Need video or picture evidence to consult…

both motors at the same time? you should try it with just one motor at a time.and yeah, a video would be helpful

Ok, I will try and get a video up tomorrow!! It’s just one motor that I can see l.
