Your year, make, model, and engine size would help everyone else out greatly. If you have a 95 or older truck, I would look into the ignition module or pick-up coil going bad. The module can be tested for free and most auto parts stores, and the pick-up coil is a simple continuity check done with an ohm meter. Second, make sure your battery connections are absolutely clean and free of corrosion. -Chris
