New Problem

Ok so I was on my way home from the garage this afternoon. I had just replaced my front barrings. Then 4 blocks from home the damn thing dies in the middle of the intersection. I manage to get it out of there after much swearing and threatening. Let it sit for a bit then fire it up and get 2 more block before it dies again. This time I call a mechanic friend who has the same model truck. He don't know. Get it going again and this time I make in front of the building but have enough momentum to coast up to the parkade door. Fight with it a bit more and get it to limp into my parking spot.
Now it sounds like it's an interruption of fuel but I have no idea weather it's something in the tank blocking the intake or a clog in the fuel lines or if the injectors are clogged.
