So, I don't know if this is on my end or not, but if I call for backup (N) after making an arrest, they will put the suspect into their car, and get in...once they are in, they disappear, leaving the car with lights and sirens on, and the suspect in the car...

It happens if you do not have enough RAM to play the game, or if you have been playing for a longer period of time. Try decreasing your in-game settings. 

Ineseri, I have 8GB of RAM...Do not think that is the problem seeing as I can play with 50-60FPS with ENB

ENB is not affected by your system memory, that's all dealt with by your graphics card which if it's a 1GB card then you're going to get texture and model loss.

Your system memory deals with processing of anything non-graphical. In other words, scripts and data. 

 

You'll typically only use about 50-60% of your system memory while running GTA IV with LCPDFR, but with a 1GB graphics card you'll use about 95% of the graphics memory, just on GTA IV alone.

 

As Ineseri has said this happens when your system is under high load, when the RAM is at high usage capacity (don't forget while GTA IV may only be using 50%, windows requires around 15-20%, google chrome uses around 10% too depending on plugins)

 

If you're running ENB you already have high video settings, so try dropping the in game ones down every now and then. If you notice texture popping or loss of models in this instance, drop the vehicle density down for a few mins.

 

Failing that, reduce the number of scripts you run, unless you're only using LCPDFR in which case you might want to reduce your play time.

 

 

One other thing, using high poly car models will affect your system memory too, the game saves everything to system memory because it's faster and easier to access. but if it's having to save hundreds of cars which are bigger and more detailed than they're meant to be it will struggle.

You shouldn't be getting too many graphical problems then.

 

What settings are you running GTA IV at?

What other mods are you using (script, data and texture mods)?

Try creating a file called commandline.txt in your GTA IV root directory and add the following contents: 

-novblank -norestrictions -percentvidmem 100 -novsync -frameLimit 0 -nomemrestrict

Not getting any graphics problems...it is just the officers go back into the cars then disappear, leaving the car there with the suspect in the back.

I didn't say you had graphic problems, but you have memory problems which that line will help improving. 

Nope...fixed it....increased the amount of maximum cops in pursuit from 3 to 10... now they will drive off...

That line will help improve memory problems, but I am glad you found another way to solve the issue :)
