First off, a big welcome to the forums! I play modded KSP most of the time, (apart from new releases) and generally can log at least a couple of hours before I get bored. Two tips I have to offer for keeping the fun in KSP are: 1. Pick your mods carefully. I can often spend hours browsing the addon releases page and often end up downloading loads of mods that look cool, but when you get to playing you may find you rarley use the parts at all. In some cases you may even have so many mods the game doesn't work at all! The key is to figuring out what you enjoy most about KSP, for me it is science, so I would try to only download mods that can enhance the gathering of science side of things like "Dmagic's Orbital Science" mod which gives you new machines and tools to collect samples and data with. For other players it may be just building, so download some mods with lots of cool parts like the B9 pack. There are even mods that help bring more realism into the game, requiring you to have oxygen and food supplies for your kerbals. 2. Set yourself goals to complete This may not just apply to modded KSP but the game as a whole. Logging on and messing about in the VAB or SPH may be fun for some, but I find that after 5 to 10 minutes, and with no clear goals it quickly becomes boring. In my experience the place the hours of fun comes from is setting yourself constant goals along the way such as: get into orbit, okay, now land on the mun, then Duna... and so on. This sense of progression is what the new career mode tries to instill in you, and is what the main part of the game is all about. In response to the crashes you have been having, KSP can only allocate a limited amount of RAM to your mods, (I don't know the exact amount) so try following step 1 and removing some less useful mods a couple at a time to see if you can get it running. This will also drastically reduce load times. If you still have technical problems, try posting in the "General Add-on Affairs" section. I hope that any of this helps, just reply if you have any questions and I'll be happy to help any way I can.
