My 68 Bus always starts right up, runs smooth all the time (normaly) but has been stalling on and off over the past several months. The van will just suddenly stall as if the ignition was turned off and leaving it in gear to try and coast/jump start it will not restart the engine. But if I turn the ignition off and then start it normally, it starts up as if nothing were wrong. Lately this has been happening several times a day! UGH! I replaced the coil 2 days ago and this did not fix the problem. It seems to be an electrical problem but I know not from where. I have tried wiggling wires at the headlight switch, coil, distributor, battery and alternator without stalling symptoms. I have a 2 year old Alternator installed with internal regulator, Pertronix Igniter and the rest is stock. I think this problem may have started after I installed the pertronix but not right away. Sometimes the problem would go away for a few months but now is pretty bad. Anyone have similar problems with Pertronix? Any other ideas?
P.S. Lights and other electrics do not lose power when this happens.
TIA, Brett
