But, people over on the E350 forum (see link above) were saying that it is not uncommon for the PIP sensor to go bad. The PIP is the profile ignition pickup (pip) sensor, otherwise known as a camshaft position sensor. Unfortunately, this sensor is inside the distributor, and it's generally easier to replace the entire distributor rather than disassemble it and replace it.
Admittedly it has been a VERY LONG TIME since I "played" with a PIP sensor or a TFI (Thick Film Ignition module), but my recollection was there were on a couple of screws/metric bolts that held it to the distributor housing. Fairly easy to replace.
Neither of theses device like high heat, but, IIRC, they would die completely (i.e. replacement was required)

Highly unlikely. The EEC-IV was pretty bullet proof.
