 Changed fuel pump, working fine, then died no warning lights - 2015 RT Spyder
Driving down the road and lost all power. Wouldn’t start back up.
Gas - yes plenty
Turns over and no start
Tach shows rpm while cranking
Lights working
No trouble light indicators
Checked fuses to fuel, pump, ecm, injectors - no blown fuses
What Am I missing or what else should I check?

Assuming, you replaced the fuel pump on account you believe it failed previously. Obviously, it may have. This new pump could be bad too.
However, I suspect you would be best off to use a multimeter and trace backwards from the pump ensuring the pump has power. Obviously, if there is power at the pump connector, and that connector has no pins displaced or failed crimps, most likely it is a bad replacement pump.
If no power at the pump connector, keep following the wiring diagram using the meter, until you determine where the power stops. You indicated checking all the sub components as good, so this adds a level to the troubleshooting.

After a thorough review - A hose came off inside the fuel pump assembly; its now hose clamped!
Thanks for the help.

Glad to read it is fixed, curious though, could you not hear the fuel pump running?
