Hello DanChycner

Welcome to 2carpros

There might be a fuel supply or a sensor problem.
Lets start with changing the fuel filter if not done yet.
Next, have the fuel system pressure done.

Position the ignition switch and the A/C system in the off position. Install a fuel pressure gauge to the vehicles fuel pressure valve. Confirm that no leaks are present, and with the key on, engine off verify the PSI reading on the gauge. It should be between 60-66 PSI (Pounds per Square Inch) If below the parameter, the fuel pump must be replace.
Check for engine code(s) if there is engine light or not because sometime engine light bulb is burned out or the code is pending and not shown yet.
TP sensor/ MAF sensor could also cause that problem.
