i have a ford f150... the oil pressure is fine when i first start it but after it warms up and i stop it loses oil pressure and wants to die. there is no knocking or ticking so i do not think it is the main bearings. any suggestions?

 

what year truck, and what engine?

 

1990 and 5.0 liter 302

 

probably the dropped oil pressure is from the low rpm during the time when the engine is trying to die.
