Just wondered if someone can quiicly direct my problem with a 95 SPI. The machine will run with a full tank of gas for about 15 mins. then it stalls, falls flat on it face and won't restart. If I bring it in and top it off with fuel and refire providing I did'nt kill the battery. It will run again for another 10-15 minutes no problem. I know it's a fuel issue but where should i start looking.
