I've owned a '65 and now a '76 midget, both have quit running while driving. Anyone?

Probably need a bit more detail for anyone to give any insight.
Those 2 would be completely different drivetrains

Both stock? Any modifications? What symptoms did they exhibit when they 'quit running'?

In my case, I have a fuel boil issue on hot days in my 75 1500
Exhibits a bucking behavior then dies due to ingesting vapor rather than liquid gasoline.

If yours is similar to mine & you're getting vapor lock on the 1500, seems an electric fuel pump is the recommendation here. I'm planning on a Facet, just need some time/$ to order & get it done.

Mine has only really exhibited it on quite warm days. No issue when it's cold out.

I'm also planning on adding a crankcase vent on the mechanical fuel pump blanking plate, hoping that solves my oil leak, which seems quite common on Weber [or most non SU/ZS carb] equipped 1500s.

Had same problem many years ago on 4cyl Ford. It was the coil. It was breaking down inside and failed when it got warm.

First, figure out if you're losing fuel or spark. Its one or the other. Otherwise the list of possibilities is infinite. If you haven't replaced the cap, rotor, plugs, and wires in a while I'd start there. Check timing while you're at it and verify the vacuum advance holds a vacuum indefinitely.

Who hasn’t? Would be more appropriate! Most of the time I’ve had fuel issues.

For me it happened twice:

1. Vapor lock
2. Manual fuel pump just stopped pumping mid trip. Whacked it a few times. Got me home. (simple check by pulling the gas line at the carb(s) and seeing if fuel comes out when you turn it over)

What I've done to deal with those:
1. Made my own heat shield.
2. Bought and installed a Facet electric fuel pump, which allowed me to re-route the fuel lines so they go straight to the carbs (twin SUs) bypassing all the engine heat by not needing to go to the pump and back to the carb.

Bucking and sputtering and dying are classic symptoms of a failing condensor, if you still have points-type ignition. As Jeff says, do a tune up, then see if it's back in the game.

It was a failing coil for me. After driving for 45 minutes or so the car would quit at the first stop sign after that. I got a new coil and all is well. The old coil worked - just not well. LOL
Good luck.

My 1500 motor would stop on the road and would start again before I could find the problem. Didn.t even have a chance to check any thing. It reminded me of a CJ I had and they both were the electronic ignition. Both drove me nuts trying to find it out, soo I am a slow learner, but I did learn so on my TR7 I just put points in right off.

Hi, I had the same “boiled” gas issue in my 76 right after w bought new. The MG dealer gave me a carb heat deflector that mounts under the carb that was standard on 77 - 79 cars; they have Cat converters, my 76 does not. Haven’t had that issue since.
