Runs... but not for long.

Have an 85 that is being more testy than my ex.
She starts up fine (well, cold natured but I choke it for a bit and then she's good... Kinda like my ex too. But back to the issue)
Took it out to go get dinner the other night and after about 5 minutes I saw the temp gauge do its normal climb so I turned on the fan (i have it wired to a switch just in case) about 200yds later I stopped at a light and she died.
Pulled over and attempted to restart with no success.
Cranks and cranks but no start.
Opened gas cap, choked, nothing.
Left it there overnight and when I returned in the morning it started right up.
This is meant to be my summer daily.driver and it is boggling my mind.

(sorry if this has been discussed in other posts. I'm on my phone and it's a pain to surf)

Violence never solved anything. Except pacifism.

Me: I prefer to take all my turns on 2 wheels.
Her: Isn't that a little reckless?
Me: Not when that's all you've got

1985 750 Plasti-dipped tins, side covers etc. Mostly blacked out.

Maybe check the battery voltage, charge voltage, and voltage when the fan is on at idle. Word is, that the ignition starts to fail when voltage drops.

check the spark and voltage when it does not start, the regulator might be failing when hot and ignition control unit could be doing the same

I'm having the same problem, except that I can usually get her to start if I crank her with WOT. Going to change the plug wires, put in iridium plugs and an AGM battery and see what it does for me. I've read on other posts that this helps.

In many cases with carbs, it can be standard procedure to open the carb on hot starts. Depends on how long it takes to fire up. If you have to hold the throttle open, and it takes a while cranking before it fires, it may be too rich for some reason.

Trying the r/r first. As well as plugs. Might relocate the r/r too.
