Starts like a Dodge?

Best guess would be a marginal TFI and/or PIP. Are both still the factory original parts?

TFI: “thick film ignition, or thick film integrated ignition.”

Depending on the model year it is located on the side of the distributor or on the fender by the driver’s side hood hinge

PIP: “The PIP signal is just Ford's name for the crankshaft position sensor signal. Now, in case you're wondering, the PIP sensor is located inside the distributor.”
