 Prodrive EFI Losing Power
37 EFI w/ heads, 308 cam, bps Q exhaust , and tuner is losing power while running. I have checked all relays and fuses. It sounds like it all of a sudden loses spark. I did have a short on the power wife from the regulator to the starter. Fixed that and it's still doing it. It will run for 3 minutes fine and then just lose all power. Any suggestions?

 Re: Prodrive EFI Losing Power
Check your ECM ground, Check your tuner ground, also make sure the yellow plug on top the HPFP dosent have wires loose inside the connector.

 Re: Prodrive EFI Losing Power
If the regulator has gotten messed up do the shorted wire would it cause the motor to lose spar? Everything seem good until that happened. (Excuse my lack of knowledge on the regulator)

 Re: Prodrive EFI Losing Power
The regulator charges the battery only. I suggest you bring it in for warranty repair.
