If no CEL (Check Engine Light) illuminated; I'm going with a massive Ground fault between the battery, fans, engine and fuel pump. Or to the fuel pump relay.
Standard Automotive Electrical Troubleshooting techniques apply here.
If you do have the CEL illuminated; use VCDS (not a cheap hand-held scan tool) to read fault codes. Repair as needed.
