Reads like fuel pressure.
Rent or borrow a fuel pressure gauge, it screws onto a schrader valve(looks like tire air valve) in the Fuel rail.
You should have about 45-55psi before turning key on
key on 65psi
engine idling 62-72psi
Rev engine to about 2,000rpms and hold it there, pressure should stay above 62psi
There is also a chance the EVAP system is plugged up, fuel pump sends gasoline out of tank but tank is sealed, so negative pressure builds up in the tank and pump can't pump as much fuel out, so pressure stays high but flow is minimal.
Loosen gas cap and drive vehicle, see if problem occurs.
A few things happen after engine warms up, one is that the EGR system is activated once engine is warm.
Remove the vacuum line on the top of the EGR valve, plug that line.
Drive vehicle and see if problem occurs.
If EGR valve opens all the way at the wrong time it can cause engine to stall out
With both the above you will most likely a CEL(check engine light) that's OK, it will go away when you hook things back up
