TS 4x2 quitting

My TS 4x2 gas Gator quit the other day while idling. It restarted after about 15 minutes, then quit in less than 5 minutes.
So far Replaced :

Fuel filter
Air filter
Spark Plug
Fuel Pump
Run with gas cap loose

After replacing the fuel pump started running great.. went 400 ft to mailbox got mail and it quit. Have not been able to restart? Runs maybe 2-3 minutes after restarting. Does restart if left for like 30 minutes.. Any ideas?

Thanks,

Dan
