My truck will start right up when it's cold and drives fine, but when it's a hot start it acts like its not getting any fuel and dies many times before I can get it started again. I've done complete tune up, plugs wires, dis. Cap & rotor, air filter. And have added fuel injector cleaner. I am at a loss and would appreciate any info you could send my way. Thanks, Dan Pitzlin

I would like you to do a fuel pressure test when the problem is happening. How old is the fuel filter? It isn't mentioned in you list of replacement parts. Also check for spark when this happens. Get back to me so we figure out what is going on.
