My truck ran for about 30 seconds then stalled, main 2A fuse was blown and while troubleshooting found that C-16 was shorted out causing the input on U5 to short to ground. removed C-16 and tested controller with stim and all looks good. The board did have a little flux residue and corrosion on it so I cleaned it with isopropyl alcohol. I have had it running for at least 4 years with no problems, is this something that just happens and I should just replace the capacitor (C-16) or is there something deeper I should be looking into?

It's not unknown for a tantalum cap to fail short circuit for no obvious reason. The price you pay for high performance in a small package.

I will order up a new cap, get my board back together ,installed and hope for another 4 years of fun, the good thing is it happened while I was still in my driveway.

We changed the tantalum caps in our kits a couple years ago over concerns of damaging them by voltage spikes. It appears when a tantalum cap data sheet specifies "absolute maximum voltage," they really mean it.
