My 5.0 EFI is acting rather strangely. Starts up fine runs well for a short period. Then once temp comes up to around 150 or so she starts sputtering and stalls. Can restart but then she stalls again in say 2 seconds. Each subsequent attempt at starting it becomes more difficult to start. Today I put it back on the trailer drove it home, about 10 minutes from the ramp, and it started right up like nothing was wrong. In previous years it has had a similar problem when it would stutter 1 time during the day them pick up and run fine the rest of the day. Although it was hard starting once it was warmed up and shut off it ran fine once stared. Are these problems related? New fuel injectors 3 years ago. Fuel delivery? Temp sensors? Needle valve on the fuel reservoir? Yes I had issues with this also! Sorry for the ramble but trying to give as much info as possible about the boats history!
