(You said) Will start cold but after it warms up it will fire but will not run. Put either to mass air intake will run but will not stay running.
It’s a loss of residual fuel line pressure. This is a common problem on any Jeep or Mopar vehicle where an aftermarket fuel pump has been installed:
Was the fuel pump you installed OE or aftermarket?
Did you replace the sock filter/screen at the fuel pump as well?
Do you know what a sock filter/screen is?
Did you know that a collapsed or clogged sock filter can cause a Draw Back/loss of residual fuel line pressure?
