Truck starts when cold ok. After running 10 minutes, it stops and will not start again till it cold again. Have replaced so many items, so many I can't list them all.
Every time I ask mechanics about it they tell me to change this or that. I thought I was a pretty good mechanic myself but this one has stumped me. Thanks J Brock

Truck is still sick. Stalls after it runs for about 10 minutes. All New Sensors, New Dist. Parts everything! All parts on TBI has been replaced.
New Computer, New wiring, WHATS LEFT?

You will need to do some troubleshooting first, to find out what is missing, fuel, spark or ignition.

Scanning for trouble codes

Are you getting fuel? A faulty fuel pump will work intermittently and then fail all at once. If the pressure is inadequate it won't run for very long if at all.

Are you getting spark? We have a good video on how to check for spark.
