2010 yfz450x electrical problem??

recently when riding my fourwheeler it will run for about 10 min and then it will start back firing and spitting and spudering and then will just shut off, it will start right back up for maybe another 5-10 min and then do the same thing but will not refire and the fuel pump sounds very weak. but it will keep cranking over just like normal it just wont fire.

I've replaced the ignition coil and spark plug cap and now it will run all day as long as i dont get it too hot or let it idle for too long, but still not comletely fixed.
