If it does start, it will idle for a few minutes, then slowly reduce idle and die. Then if I try to start again, it will just crank and crank like it is fuel starved. I replaced the crankshaft position sensor a few weeks ago. I thought I had it fixed. And yes, I used a Bosch sensor. When it starts and I drive down the road and back, It will still slowly reduce idle till it dies. Can anyone point me to a good starting point?? Thanks in advance..... oops, it is a '04 n/a

 

I think I would start with a fuel pressure gauge on the system. See what the pressure readings are as the issue arises. Process of elimination.
