Given the size of the property and age of things.. I doubt a restrictive HOA is in play here

I wasn't thinking HOA, I was questioning zoning and home owners insurance policies, so HOI? Our lots are huge and not a new area by any means, we can't even have a trampoline.

Zoning would matter if they were charging admission, but I'm sure there's a blanket statement somewhere to prevent this type of thing. Since it's behind privacy fences, it's not a visual intrusion though.
HOI would only care if someone other than the property owner were using it. You can't sue yourself, so property/liability insurance wouldn't come into play if you got hurt on your own roller coaster. Now, if the neighbor gets hurt on it, there better not be a claim, or it will turn into a huge mess.

See, where I am zoning prohibits what is placed on property, zoning varies everywhere, sometimes even in the same city. For single family parcels we have R-1 and R-2 zoning laws. R-3 is the catch all for parcels that multi family or have a HOA. Zoning laws prohibit trampolines and nobody charges to use them. Same with swimming pools, they are not allowed in R-3

Your coefficient of friction is probably too high. Which means you need to:
1. Increase the angle at which the coaster heads down the incline plane (Which you may or may not be able to do; it's already pretty steep) or
2. Decrease the friction. You can lubricate the tracks, the wheels, or both. You can also decrease the force holding the wheels onto the track.
Hmm. Perhaps physics was useful for something

That track length has no chance at all (all the curving back into the woods).
There isn't enough energy pickup in the drop to support all that given the climb back after the drop. A PVC system is going to be too lossy due to the losses in friction in the wheels and track system and movement between the track and wheels.
The change in direction at the bottom is far too aggressive for a system with so much slop in it. You can build up your wheel shuttle system, but your track will probably not be able to take the load from the change of direction. It's too flexible and will probably rip itself apart trying to take the load.
Decreasing the slope of the hill will probably get you further as it will reduce the acceleration that the system needs to support. Reduce flex/movement in your wheel system.

Decreasing the slope of the hill will only increase the amount of friction because it increases the time of getting down the hill. I would not recommend reducing the slope.

You lose energy due to friction due to the run distance... but you also get a system that will actually work. They aren't running out of energy - they are derailing because the system can't take the forces involved.
By increasing the acceleration - they also increase the forces the trolley system must control.. and actually increase the friction/energy loss in that change of direction.
Their design is overly ambitious given the space and speed they will be running at. Without a solid trolley system they will never make those banked turns or changes in direction without derailing or losing all their energy due to the slop.
Banked turns require speed to keep the force pointed outwards towards the curve. Taking them too slow and the velocity vector doesn't overcome the gravity vector and you basically tip inwards losing energy and probably falling off the cart.

Maybe when I'm not so busy I'll use Roller Coaster Tycoon 3 and run a simulation for them.

I'll rely on the engineering program I actually went to
RCT isn't going to simulate the slop and inefficient trolley they are using.

You have to build all these first. 
Believe it or not the track hasn't broken due to force yet, only the car wheels.
I want to do this, but my computer is too new for the old game which is frustrating.

Really? Huh. RCT3 runs on my Windows 8 and 2 ran on the 7. Thursday night I'll get on and run the simulation. I've had the strong desire to play that game anyway. I think it should work and that you need to reduce your friction, but I'll check it anyway
It worked for a while and then one day it stoped working and I haven't been able to fix it. I tried it on a Mac too but that didn't work either which made me mad. Can you do a screen shot video of the coaster on rct3 and upload it to this forum?

Yes. Of course. I can do it for you on Thursday evening.
