How old is the gas? Plug wires on correctly? How long has truck sit not running?

It sat for a little over a month with half a tank. All plugs and wires are right, they were replaced about 2 months prior to problem as well. It started about a week ago and ran for about 20 minutes spitting and sputtering.

I'm leaning to water in the gas also. Try pouring a teaspoon of gas in the carb and see if it starts for a few seconds

when you add good gas remember to undo fuel line at engine and allow fuel pump to pump all bad gas out of the line. Do this till you smell good fresh gas coming out. Make sure to catch the gas and not get it all over the engine
