This is the strangest thing I have ever seen. I start the truck and it runs perfect, no issues at all. This may go on for 1 to 20 uses then I will start the truck and it stalls repeatedly and if you drive off it will almost die then I can pump it and it may come back to life for a few seconds to several minutes then it will almost die again. I have had it to the local garage several times and they can't find anything wrong. I even had the onwer of the garage take it home and drive it for a four day weekend, no problems at all. It almost seems like its starving for gas. The way it comes and goes leads me to think its electrical. I can't trust the truck to use it because I can't get left somewhere. PLEASE HELP ME
