Van has been cranking when cold, rough idle, runs for about three miles then shuts down. I have to wait four to five minutes cranks up and go on my way with skipping but drivable, sort of. I have replaced plugs, wires, coil and camshaft sensor with a slight improvement but still hard to start and skipping is still there.

This sounds like a crankshaft sensor is going bad but it could be the PCM as well they go bad on these cars.

Here is a guide to help you see what you are in for when doing the job with diagrams below to show you on your car:

I have changed the crank sensor and no real change. The codes are now 12 13 54 43 54 55. This plug was one reason I thought it was skipping. I thought maybe too long a plug even tho I had a mechanic put them in. I have placed shorter plugs in to replace them. Autolite 437. They have not changed the skipping at all so unless you say I should change back to the longer ones I will leave them be for now. This is not the only one or only time I have changed the plugs and it ran fine afterwards but now no change. I have had the porcelain from some other plugs completely missing. New plugs have always fixed it up until now. Detonation maybe? I do thank you for taking time to help with this.

Yep that is a problem here is the correct plugs the engine needs to run right.

Spark Plug .................... RN14PMP5

I would install those first also lets do a compression test as long as you have the plugs out. Here is a guide
