'06 Tacoma 4WD 4.0L Random Hesitation During Acceleration

For anyone who can help...I’ve had a random hesitation on an ‘06 Tacoma that started about four years ago, about a year after I purchased the truck. Since the hesitation started, it’s never throw a code and I’ve changed the spark plugs, replaced the throttle body sensor, checked and changed any fuses, replaced the MAF sensor and the PCV valve. Each time I’ve replaced or worked on the truck I’ve reset the ecu. After resetting the ECU, the truck will run perfectly for about ten or fifteen minutes and then go back to the same old. Nothing has fixed this random hesitation permanently. The last two things I can think to do are replacing the remaining two original oxygen sensors or replacing the fuel pump. Any suggestionS would be greatly appreciated!!! Thanks in advance!
