engine started stalling after driving for 5 minutes...just shuts down, but get some hesitation leading up to the stall. Wait 40 minutes and it will start again, but shuts down more quickly...shorter time. Sit overnight, starts right up runs 5 minutes stalls again...same scenerio. Replaced fuel filter...same problem...replaced air filter, also.

Hi koolhanl, Welcome to 2carpros and TY for the donation

Do a fuel pressure check and monitor it-the pressure should be 9-13 psi-let me know
