Have we covered the basics like a standard tune up? I ask because you
mention it's newly acquired. Seemingly decent cars (vans) can fail to
run if the plugs are worn down, the filters are clogged, etc.

Also run a double dose of Techron through the gas on a half tank of gas,
it's a good idea to change the oil after a high dose like this as it
will get some past the rings and into the oil.

Besides the above I would recondition the electrical grounds in the
engine bay as they often get nasty over time, reducing over all
electrical output and restricing a full burn at the plugs. Battery
posts/ clamps cleaned and coated with at least a ligh coat of vasolene
(if not Stabilant-22) and the starter to battery, Alt to battery
contacts need some TLC too. (Do a before and after test with a
multimeter- measure accros the battery terminals during Idle. 12.5v?
Just barely enough. 14.5v? On the high side, but I'll bet you won't find
it.)

Makes for a smoother running motor. Even if none of this fixes the
problem you should still as it falls under 'new to you' viehcle. Right
up there with changing ALL fluids.
