Probably not the ignition switch if it died while driving. You will need to fall back to basics and trouble shoot. Does it have fuel? Does it have spark? Does it have compression? Is the timing OK?

I'm not sure how you did the 12v conversion, but it appears to me that you have two problems. 1. Gauges could be a blown fuse, or some other defect in the converted system. 2. If the engine shuts off while driving often, then, Yes, it is extremely possible that it's the ignition switch; especially if this happens when turning the truck or hitting a bump. An ignition switch is just an electrical contact. A worn ignition becomes loose and the contacts can easily separate enough to lose contact and kill the engine. Sometimes it's so brief that you only notice a momentary pulse in the engine and it keeps on running.
