i started to notice occaisionally from a dead stop my b2 would bog down and fall on its face when trying to accelerate then after a moment would be fine. so i replaced the fuel filter now 3-4 weeks later i went for a drive and filled it up with 3 gallons of non ethanol 91 octane and 5 gallons of regular.( it was a little low on fuel so i figured it was pickin crap up out of the tank from using seafoam)

it ran decent after that. I drove around a while longer and shut it off in a parking lot for 30 mins. went to start it and it would run for 2-3 seconds then die. eventually it started and i went for home. it was low on power and popped out of the tailpipe.. died 200 yards from my house.. luckily neighbors where outside and gave me a push. got it home and poked the shrader valve on the fuel rail and it had fuel pressure and could hear the pump but engine wouldnt run... the next day it starts and runs fine. :icon_confused: Could it be bad fuel or possibly my pump starting to give out? not sure where to start checking stuff.

It sounds like your TFI module. Check some of the thread regarding the ignition control module. Usually if your TFI is going bad when it's hot the engine dies and when it cools off the engine will start again.

I am not the best at these because I am not a mechanic.

None the less, why do you feel the fuel system is the culprit?

I would first find all things that can cause this problem, then start to rule out from there based on the information the engine gives you.

From my understanding you have fuel pressure, and the pump is working from the sound of it. Could you have another problem that is causing these issues. Perhaps a sensor?

it had fuel air and spark. at the moment it still runs but not as well as before the whole event. even prior o the event when cold starting it wont start the first inition turn of the key. it will almost always start on the second.

On the fuel rail is the Fuel Pressure Regulator(FPR), it has a vacuum hose attached, pull off the hose and check it for gas or gas smell.
When the FPRs get older the diaphragm can leak and fuel is sucked into the intake causing different issues, bogging, slow starts, flooding out after short time sitting.

The TFI ignition systems get heat sensitive as they get older, good read here on checking those out:
