1, as Nobotada said it could be bad fuel, I am willing to bet that what was in the tank as soured after all this time, I would suggest at least a 5gal jerry can of some fresh gas. second to that it could be a plugged fuel filter or a failing fuel pump.
2, it may be an issue that has plauged my bonnie, one or both of the crank angle sensors could be bad, my car would run for awhile then randomly shut off, and some times I could start it right back up but sometimes not.
try the fresh fuel first and if that seems to let it go farther then I would suggest to get some fuel injectore cleaner and take it to the gas station and give it a full take with the cleaner in it and hope for the best. if that doesnt work then I woould have someone look at the fuel filter and the pump to make sure its clear and the pump is putting pressure out. I dont even want to think about the crank sensors.
good luck my friend
