When i first start the car. I can drive it for a few minutes while the engine is still cold. Then after its warmed up i get a drastic loss of power and sometimes backfiring and stalling. Iac recently cleaned and tps replaced. Checked fuel pressure. Cold idle= mid 60psi
Hot Idle= 30psi
While driving= 10psi

Its looking like a bad fuel pump. Just wanted to get more opinions. Thanks in advance.

Easiest possibility is fuel filter. Replace it, see if the pump is really at fault. That, combined with bad Engine Coolant Sensor could cause your symptoms. imp
