You could use some flexible rain gutter downpipe to create an air ram to force cooling air from down below up into the lid. Some turbulence there would keep it quite a bit cooler. Probably more effective than making the box larger.

While I understand the dismay at having the van quit on the freeway, You seem to be putting a lot of thought and potential effort into this project based on an extremely intermittent (once) electrical gremlin. Problem is that you could pour bunches of bux and time into it and still not now whether you fixed it. The real killer is after you've made that investment and you're happily driving down the road and it happens again! Don't ask how I know about this.
