Need help with my 2007 Rhino 660

My 07 Rhino runs well at idle but when I take it out it will run for 3 min and it quits. I can start it right up again and go for another 3 min and it quits again this can continue on and on. I changed from the vacuum fuel pump and installed a electric fuel pump from Black Rhino (installed a power block as well) so I wouldn't have a power issue to the fuel pump. I have installed clear fuel lines to monitor fuel flow, I checked all of the vents.
It ran well when I bought it in 2016 (took a long dusty ride with friends and it ran great (it was just hard to start after sitting for a couple of days) then it started to stop when I was out on short rides (of course with the wife, no fun at all) I would let it set and it would start up again. I found old cracked fuel and vacuum lines, I replaced them all, changed fuel filters and would think that I fixed it I would go out again and problems are still there. This is when I decided I would solve all of my problems and went to the Electric fuel pump got it installed and took it out for a test drive and start it up run for 3 min and it stops. Does anyone have any ideas? Carburetor? Float valve? I called Black Rhino to see if the pump had an internal pressure regulator (overpressure the carbonator) I was told that the pump is very low pressure and doesn't need to be regulated. I need some ideas that I might be overlooking.

When it diess, does it sputter at all, or dies completely....a sputter when it dies can indicate fuel issues, full on going dead may indicate electrical component....maybe electronics are overheating, then cool for another 3 get the idea.

Next time it completely dies, get out real quick and loosen the gas cap and listen for a quick sucking sound .....or if you have less than a full tank, loosen cap to allow air in and drive it...see if it reacts differently

Your main quest is to determine if it is fuel or electrical issues.
