Is it possible that you overfilled your tank? If so, this may have been the cause of your hesitations.
By adding more fuel after the nozzles initial shut off (filling to the brim or topping off) can cause damage to evaporative emissions system or render it inoperable. “Topping Off” may cause fuel to enter the charcoal canister, or carbon filter, which is designed only for vapor. By digesting the fuel rather than vapors will cause engine stalls until it purges itself of fuel, or it is replaced.

Dave,
I do the same thing. I have a big bottle at home and refill the small bottle, which I had with me which I added when I refueled after the episode. Over a thousand miles later and it has not happened since.
I am guessing that in your MG you may experience "vapor lock".

I was chatting with the owner of a MG repair/restoration shop and asked him if he had any narrow insulation spacers as I was thinking I would move my SU carbs further away from the heat of the exhaust manifold. He suggested adding Star-Tron to the gasoline. I plan to test it out starting tomorrow; heading to warmer temps.

It happened to me again once on the drive this weekend at the Hagerstown Meet. I again, added Lucas fuel treatment on Sunday, and it has not happened since I filled up at the Costco with Top Tier 93 Octane fuel in Frederick, Md.
Does anyone have any thoughts?

Have you tried cleaning the IACV valve? Here's a link:

Matt, Not sure if your car was manufactured after they fixed it, but AP1s did have a problem with the MAP sensor which caused stumbling and stalling out at idle. Most people whack it to try to fix it, but you actually need to use a zip tie to hold the sensor tight to the plug.
