Question edited for clarity.
Question moved to model category.

The 1994 does according the video, so it is likely your does as well.

bad solenoid.

My first car was a 1969 Dodge Coronet station wagon with the 318 cubic inch engine. Loved it!
In my experience, the most common reason for this behavior is a bad crank or cam position sensor (assuming your car has one of those), since they tend to fail hot.
Another possibility is that a dirty or worn ignition switch is supplying power to starter, but not the engine, when it gets warm. Try spraying with WD-40 to see if that helps.

Should be on the valve cover.

Your best bet is to search it online on your computer.

When you say new engine I have to assume we are talking a manufactured short block engine. Here is a list price of just such an engine:
CHRYSL 2 122 4 C 2000-01 Neon, Stratus, Breeze,FWD,SOHC, MFl, 16 Valve,upper blk #642,651,lower blk #769,head #737,crank #755,valve cover has 10-6mm bolts, extra 8mm bolt under #2 &#3 intake port,with water pump Head part # call DD91 $1,990
Here is a page you should view for brand new engines as a comparison.

If your going to get a manufactured short block engine replacement, and an engine computer along with a new battery AND labor you are getting a fair price.

Thanks for using FixYa.

It should be on one of the valve covers. I think it would be on the driver side one.

If this is a van you will remove the cover from inside the van. The center cover comes out and you will have full access to the engine. Your manual should show you how to remove it but it is usually very simple. Hope this helps.
