or bike engine
sorry, i might as well get the boring and predictable comments out the way first
And you run and you run to catch up with the sun but its sinking, Racing around to come up behind you again, the sun is the same in a relative way but
your older, shorter of breath and one day closer to death

Have you cleaned the fuel filter(s) out?? Chances are there is swarf in them from the fuel tank being new. You do have a breather on the fuel tank
dont you???

Is it a 'cough - cough - splutter' type of cutting out, or a "now it's running - now it isn't" event?

Does the distributor have points, if so is the dwell angle correct? ? If you have points are the contacts blue? If so could be a faulty condensor? Are
you using a ballast resistor and matching coil? a ballast coil without the resistor will cause problems with the points/condensor. Do you have a
spark when the engine dies? Have you got fuel to the carb when it dies? Just a few things to check .
Might be worth putting your whereabouts in your profile

What is the carb.? webber, solex, standard.
When the engine stops, how easy is it to restart ?
Ive had a similar problem to this on two occasions, one resulting from a piece of debris moving around in the tank and occasionally being sucked onto
the fuel pick-up pipe cutting off the fuel, the other was a damaged float valve in the carb which failed to shut off properly and allowed the fuel
pump to force feed the engine. This made the car go like stink and worked fine until the engine warmed up, at which point the car would stall at
junctions and would be a sod to restart - it was gassed up.
If the engine stalls after about 2-3 miles, this would seem to coincide with the engine getting up to temperature. Sounds more of a fuelling problem
than an electrical one.

Next time it dies, take a plug out (probably will be hot!) before carrying on. If it's sooty black or wet with petrol then you may have got a
problem with over-fuelling. If it's bone dry then maybe it's too lean a mixture. An ignition problem can show as a wet or dry plug! 
This does require that you carry a plug socket, of course...

Check the points, and the coil - if its after a few miles, chances are the ignition system is overheating, when my coil was fubared i'd get a
few miles then it would start misfiring, hesitating and generally running like a bag of nails.
Strongly recommend megajolt if you haven't already fitted it, takes all the black magic out of ignition timing.
