Truck has 113000 and has been running like a champ. Still runs great - but stalls after driving for about 20 - 30 minutes. No warning, runs great then just stops. Thought it was related to temperature - but about everyother start-up truck won't run at all. Then after a little while it will start right up again. Replaced fuel filter, coil, cap and rotor, checked sparks, etc. - Everything seems fine - until it just stalls without warning.

Check the fuel pump pressure should read 3-5psi. Fuel pump checks out.

Test for spark when it stalls-No spark could be the ignition control module or the distributor pick-up inside.

Or the ignition switch is failing
