Car dies and wont start

I have a 92 grand voyager with 150,000 miles on it it is a v6 It just started today. At first it would make a grinding sound when you started it and it would run for a minute and then would die. I could grank it over but it seemed likr there was no fuel getting to the engine. I tried to start it again this evening and there was no grinding sound and it ran for a minute but died and it turned over but I could not get it started. I changed oil about a month ago and the radiator relay moter was changed about two months ago but no major engine work has ever been done on it. It is our only car and it has a lift in it for my wife and we cant do without it. Can you maybe give me an idea what is wrong with it PLEASE. :(
