Not sure what to call it, any reasons I might be getting the bumps at the end of straight cuts?

Similar to what /u/early_sound suggested, my money is on overloading of the cutter/machine. A simple test for this theory is to repeat the part with lighter passes. (Are you cutting full depth in a single cut?)
Note: You could also slow your feedrate but that would likely mess with the calculated chipload more and there are chipload calculations for a reason. ;-)
If the "bumps" go away with lighter passes, it's almost certainly (I can't think of another explanation at the moment) overloading. Now, what is being overloaded? That's a different set of experiments. The most likely culprits would be the machine axes themselves (X, Y, Z) or the router/spindle.
