Is the Check Engine/ Service Engine Soon Light on? If so the computer in your car is going to have relevant information stored in its memory which will help figure out what is going on. A scan tool is needed to retrieve this information. A professional grade scan tool allows key engine sensor data to be analyzed right off the scan tool without having to do intrusive testing at each sensor. It sounds like you may have an ignition problem or a vacuum leak, possibly even a fuel delivery problem, it could be many things, unfortunately and without experiencing the problem first hand or being able to do some basic diagnostic tests its hard to say.

A professional grade scan tool has what is called Mode 6 diagnostics and allows you look at live sensor data as you drive. It is here that you can pick up things that are marginal but have not set a trouble light.
check your fuel filter sometimes it has trash in it causes your truck to loose speed and make it shakes try that first
