Running less than 5 minutes generally leads me to believe fuel starvation. Couple of things to check.
1. ensure all fuel shut off valves are open.
2. double check for leaks or weeping around filters
3. how much fuel is in your tank.
Re: 1 So my train of thought is that a valve is not open fully and the pump is having a hard time pulling fuel.
Re: 2 Maybe a line clamp or seal is sucking air into the system depleting your fuel pressure on delivery. Double check your work there.
Re: 3 "if" you have a pinhole in your pickup tube (the actual tube that the gas comes from the bottom of the tank) your pump might be able to fill the fuel filter and carb for start up. However, once the engine is running the pressure in the line drops off because you are using the fuel...and the engine stalls. You go for restart and the pump is able to re-pressure the line. So, in this case you add more gas to the tank and see if the problem goes away...if it does you know you have a pinhole in the pickup tube.
