Freind of mine had exact situation. Starts fine, but immediately stalls out. Every time. Start and stall, start and stall. Turned out to be fuel pump seals or filter basket or whatever - in the fuel tank where the pump is - they crumbled or dissolved and fell to pieces and blocked passage of fuel out of the gas tank and into the fuel line. What worked was having a mechanic replace the fuel pump (with its new seal or filter basket or whatever comes with it). Fuel pump was not expensive ($45?). Getting inside the fuel tank seems to take a bit of time and might cost several hundred in labor. But this one thing fixed the situation for my friend.
