Well i will just start this thread with what my fuel system consists of...
I have all braided-8 lines from front to rear eliminating all factory lines. I am running e98 and have a full tank of fuel with a Full Blown Double Pumper hanger with 2 Aeromotive 340's feeding the pig. The car has a very conservative 35 psi tune on an AEM V1 that Jordan @ MAP kindly did for me. The second pump is triggered by a Hobbs switch that we are very certain kicks on under boost. Right before we were going for a cruise we briefly did a good solid pull and then just cruised which no more than a minute later the main pump just stopped running. There is power at the pump and before i go ***** deep into removing the mess i want to assure myself that i am making the right decision by removing it.

Could it be the ignition switch that triggers the pump to turn on?
No fuses are blown.
Could a relay fail and cause it to not turn the pumps on?
Has anyone ever had an issue with this?
Could it be a hanger failure or from too much vibration the wires simply came off?
Or am I just that one small minded idiot running e98 through a factory fuel tank?
Could it be the AEM?

Any advice or suggestions are certainly welcomed!

Thanks,
