My 95 gt stalled and wouldnt start!!

I pulled in a gas station, came back out, started my car and drove maybe 20 feet and and just died. Went to start it and wouldnt fully crank unless i gave it a lot of gas.

Let it sit for a minute, checked to see if it was vapor locked, waited about 30 minutes and still nothing, only if i keep it rev'ed around 3000 it will stay running. The car is in the shop now but wanted to ask you guys what it could be in case the guy at the shop says a lot of different things, thanks

no i didnt, the shop just called me and said they cant find anything wrong with it though, now it starts fine, but this has happened 3 times before in the last month, think something could be overheating?, the temp gauge is normal though.
