particle age UVW gradient
#3
Did you look at the UVW Gradient official sample scene? That's the standard way to control particle colors by age or other triggers.

I guess your setup is slightly different because you're not controlling particle colors on the whole, but instead having a gradient travel up a spline once triggered. That's an interesting dilemma....my intuition would be to have 2 map channels...one to set the UVWs required to have the gradient go from bottom to top, and the other to control the V offset of the first channel (this would be what you control with particle data). Might have to involve some OSL as well to get it to work (read the V value of map channel 2 and apply that as an offset to the V value of map channel 1).
