so I have a simplified system, 12a, IDA 48, MSD 6a going through the dizzy, so no emissions, air pump, hot start assist, any of that, and it has ran for over 2 years with this setup, the car still runs fine, starts instantly hot/cold, i just checked the compression and its 115psi all round, and symptoms are constant with or w/out the MSD.

what seems to happen here is that when I take off after restarting the car after only letting it sit for a few minutes to a 1/2 hour (whenever its still slightly warm), it seems that it is not getting spark/ignition for some reason, shortly after i take off even if i rev it up in the parking lot a few times and all seems good as soon as i pull out and start to pick up speed it quits, i assume this as when this issue occurs, the engine tone is quite different if i leave it in gear and coast(cant hear combustion just compression), if i take it out of gear it dies instantly, now what makes me think its no spark is that to start the engine again, all i need to do is turn it off completely, and hold the accelerator pedal to the floor and crank it(de-flooding a rotary) it starts up with a cloud of smoke and a few stumbles, but now shes off to the races like nothing happened, and its all gravy again until i have to go through it again?

am i looking at an ignition/carb issue, i have went over the carb extensively checking settings and changing up jetting, but nothing gets any better or worse in regards to this situation, i am starting to pull my hair out over this as i have treid many ignition configurations as well (stock ign coils, msd blaster coils with and with out 6a,
throw me some ideas please

so when reading through recent posts in a thread about adding a bypass regulator the issue of vapor lock was discussed, i had not heard of this issue, and realized that i had installed a thermo control to automatically shut of the electric fan when not needed, just prior to this issue arising. so last night I set the fan to run full time, and my stalling issue seems to be gone........so i hope it was that easy.
