Latest update: definitely vibration related. I still believe temperature plays a role, but I¡¯m on a test drive now after replacing the ignition relay. Ran fine as usual for the first 10-15 minutes. It blew right after rolling over a minor bump - but with the vans suspension everything is felt. Replaced the fuse got back on the road and hit a slightly more significant bump and the it blew again.?
About to peak at the starter wiring.?
