I have a 1991 v6 Toyota. Recently i have been having a problem at times when i push the gas pedal the engine loses all power. the truck doesn't stall but it has NO power not even enough to move itself I'm open to suggestions Thank you all

 

check ignition timing.

 

That is the first thing i checked .

 

I'm having the exact same problem driving down the road when it happens I can turn my key off and turn it back on and we'll pick up and run to problems got progressively worse not sure what to do I'm sure it's a sensor but don't know which one could use some help as well
