Minecraft keeps crashing

I am currently running 9 ADD-ON in my game which consist of 1). Another furniture add-on, 2).Dragon Fire Add-on, 3). Uncrafting items add-on, 4). Lucky blocks evolved add-on, 5). Evolving weaopns add-on, 6). Storage+ add-on, 7). enchantments plus add-on, 8). Ore armor and tools expansion RP add-on, and 9). More ores Tools armor add-on. After playing for a while the game crashes every 10 min or so but is still random. i have copied mu world and removed the dragons and it seems to have fixed the crashing issue but is not the original game i created. I have tried to move the recourse packs around thinking that would fix the problem but it did not fix the issue.
