Loss of power

[Bubbag007]

70 Bronco sport, 302. Stalls while in motion as well as at idle sometimes. Will not restart if I downshift and dump the clutch, but will again by turning the key, then will die off and on. I have replaced both the Ignition and switch already. What should I try next?
Thanks,

Check ground from battery to block and block to body/frame?

Hi, start with the basics, spark and fuel. If you have an in line spark tester you can see if the spark is dying out.
If you can't remember when you changed the fuel filter, do it now. If the ignition is original with points and condenser it may be time for a complete tune up.
If it sat all winter the gas may be stale, or full of moisture.
When it is dead I would check for current at the positive side of the coil (key on, just as it stalls).
If you have a tach I would remove the tach lead from the distributor side of the coil until you get this figured out.
Check that out and post back what happens.
Good luck

Looks like it might have been a loose wire from dist to battery side of coil. Just had electronic ignition installed and the wire connector seemed loose. Hoping that fixed the issue. I will re-post if not.
Thanks,
