70+ for 2 hours? Doubtful it's a gas cap venting issue but stranger things have happened.

My personal experience has shown the Compufire Ign. can and will fail but it won't kill "everything". So again, in the interest of clarification, when the engine dies do you still have lights and all running electrics alive?

Why? you might be asking. Because a mains failure will shut down an engine quickly but it also takes "everything" else down as well and self-recovery after a few minutes can be typical of some breakers when affected by heat.

A consideration to note, your Compufire may be expanding from engine heat and opening the trace on the printed circuit board when it expands (bends). I had a taillamp circuit board do that on my 07.

Wonder if the previous owner ever experienced this issue?

Gday to you! I know a Constable Supervisor from NSW. I won't tell you how. I would love to spend about 6 months in Australia riding adventure bikes and hunting bush bulls and hogs!

Hello. One of my oldest friends lived in Spring until very recently. I used to drive my jeep down there and we would visit some of the off road places.

Thank you. I desperately want to do some fishing and, if I could afford it, some hunting in Canada.

Thanks! I got lucky in the early 90's and drew mulie tags for Idaho,  Wyoming and Montana. I fell in love with all three states. The people I met there were incredibly kind and generous. Not something I was particularly used to coming from South Florida. The elevation nearly killed me but, I enjoyed every dizzy moment lol

Well,  I checked the battery terminals. They were good and tight, the cables are good and the ground strap is tight to the frame. 

I wiggled the ignition switch and connections with no results. 

Then I drilled the rivets out of the cam cover so I could take a look at the non points system inside. To my surprise, there wasn't a cam position sensor like Rigidthumper showed. Instead, I found what I believe is an electronic ignition module. I will post a photo if I can figure out how to do that. 

It may be possible that it's a tank venting issue but, just a few days ago,  I this bike at 70mph for more than 2 hours trying to get an ideal of fuel mileage (37mpg) with no issues. I would think it would have choked at that time if it were a vent issue. However, it does have what I believe to be aftermarket caps so, I guess it is possible. 

There should be instructions that state which ring type is top and second, as well as what coating if any is top or second. There should also be instruction showing in what orientation if it matters is up.

Below is from their V-Twin (Harley Davidson) catalog. The rings should have a type listed on their package, GFX, VM, VQ, etc.
