Default Cause of LRP V6 speedo meltdown??

Question for the forum: Racing stock TC with my xxx-s yesterday I had a meltdown of my LRP V6 speedo in the second heat after only a few laps. I mean a total meltdown, case crisped/melted down around the FETs, enough smoke for Tonto to send smoke signals to the next mesa, etc. But I can't figure out what caused it ... I'd been running the same motor/gearing the last two weekends without any problem. The motor was an almost new P2K, 30T - 48 pitch pinion (sounds tall but it was topping out on rpm's about 3/4 down the main 90' straight) and I'd kept it clean and oiled. The motor was hot, as usual, but not too hot to lay a finger on it for a few seconds. No binding in the chassis/drivetrain. So, I can't understand why the sudden failure?!?

Anyone else have a V6 meltdown for no apparent reason? I've had this speedo for over 2 years and never had a problem, even with mod. I have a good spare V6 to put in, but I'm worried I'm missing the cause and "history will repeat itself". Any tips or info? Was it simply "its time" and just one of those things?

I would pack it up and send it back to the manufacture along with a letter explaining what happened. You never know they just may replace it.
