Question type: Maintenance & Repair

Driving down the road truck acts like it doesnt get gas and
shuts off. Sometimes it will putter first then shut off other
times it wont.  When it putters you can easily press the
gas and it'll go away but if you press it to hard its worse

Probably a fuel pressure issue, or a vacuum leak. Fuel pressure should be 9 to 13 lbs. and I have seen the TBI base gaskets go, so check the base gasket also.
