It was feeling kind of weak this morning, got to work. Went for a drive to the other location, came back, turned off my car, when 5 minutes later went to start it up again. It turned over, but wouldn't start. Took a few tries to get her started. then she started, went to the other location, turned it off, and when i tried to start it, same problem.
Then on the way back to the home location, when it got to 4000 rpm, it started sputtering, so i pulled over. It idled fine. Then i hit the gas, went to 3000 rpm, and sputter, then 2000 then started sputtering at idle, and eventually died. I waited 10 seconds, started it up, and it started fine. and drove too.
Drove it for 5 minutes, and it didn't die. Does anyone know what is wrong?! I'm thinking fuel pump, but of all the fuel management parts, that's the most expensive,
