Best thing to do is go to an Auto Zone and have them scan your truck for any DTC codes. Auto Zone scan free of charge, there is just to many things that can cause the engine issues your running through such as detonation during acceleration due to timing issues to lack of fuel pressure. Good luck and keep me posted, be glad to help you get your truck running 100%

When accelerating fast the engine cuts out suddenly then returns to normal multiple times. If I try to accelerate at a lower pace then it works fine. It feels like an electronic problem


Engine ECU is provided with a high RPM ignition cut off. Perhaps that is what is confusing you. When you accelerate at a fast rate, probably you get higher RPM's and the ECU cuts the ignition to protect the engine from damage.

Lack of power


There seems to be some kind of fuel (gas) starvation, check the fuel filter, check to the fuel pump could be weak.
Check the spark plugs, the condition of them will give yousome direction to go about it all.
If its whitish =lean means lack of fuel (gas) and by your explanation it should be whitish.
If its a carburator model thn it may need cleaning.
Not bad to check the distributor too.

Hope this helps!
