Speed reaches 50mph starts to shake or jerk

My Tacoma indicates codes p0325 and p0336 and it loses power when starting and after a while, it suddenly develops. I've already changed the crankshaft sensor, candles and wiring but it is still the same.

I was going home and all of a sudden my toyota had came to a rolling stop I can push the gas peddle and the RPM's go up but truck will not move I can shift threw gears but there's no move ment at all was told the pump was bad so I changed it checked the neutral safety switch. Still nothing...

I have my tacoma with 96000 mile in it. Got it maintenance at a local toyota service center. They replaced spark plugs. After a few weeks I noticed that between 40 to 60 miles per hour my truck had a jerking or hesitation move. I physical check the 6 plugs...maybe it wasn't gapped correctly but they were. Also checked ingintion coils to see if they were burned or had any oil around...also looked fine except one of them was marked with an x in yellow. Scanned it as well an everything checks out or no engine light has turned on. What else could it be??

RPM DROPS down to the point of stalling out at the light. Doesn't "idle up" when turned on.

Truck runs fine then bogs down and can’t give it gas then dies might start back and run fine for a week maybe two then does it again track light comes on and engine light I’ve replaced both fuel pumps crank sensor fuel regulator and fuel control module

My truck. Will smell like something is burning. Then it will lose power. After that the breaks will become hard to press down on. But no dash lights come on and the code reader won’t find anything wrong. Took it to Toyota mechanic twice. Their systems don’t find anything.
