Aloha and thank you, Mike.Just a hunch here based on everything you have already checked. I think your 95 5SFE engine still had an internal coil inside the distributor. If it does, remove the distributor cap and rotor and then remove the coil. Check the underside of the coil for hairline cracks. These generations with the coil internal to the distributor had a habit of developing hairline cracks over time and shorting themselves to ground on any metal inside the distributor. This would be worse under load as when accelerating and in damp weather.
I was just now onlining some research about testing the coil as CamryFl said I should, so I will be pulling Dcap, rotor and coil to check and test. Back at you all helpful people later.
Mahalo and Aloha,
