I used the Flyman pump assembly, you end up removing/isolating the 2nd pump wiring.

Just wanted to make sure that you had a factory two pump set up and replaced one pump or had a new single pump set up. OEM dual pump set up will run fine until magic coolant temp and stall out if the primary pump has gone bad Sind secondary pump turns off. We can rule this one out.
