After truck is thoroughly warmed up (15-20 minutes), it will frequently die when making a sharp turn (like off the street into my driveway). It will not restart immediately (it just goes rrr. Rrr. Rrr) but after only a minute or two it will start like nothing is wrong.

Hi azbob,

Thank you for the donation.

Do you mean the starter is not cranking when you tried to start it?

If yes, then you have a possible fault with bad ground connections or wiring.

Check for bad ground connections and loose or contaminated wire connectors.

The starter is cranking (if my understanding of the definition of "cranking" is correct"). The rrr. Rrr. Rrr is the starter turning over. That defines "cranking" to me. At this point it is acting as if the battery was down to its last volt. But the fact that it recovers in only a minute or two would seem to eliminate the battery as the suspect.

Cranking means the starter is turning the engine.

It is possible for the battery to be bad. Maintenance free batteries can fail intermittently, is good one moment and fails the next.

Check the battery terminals for contaminated or loose connections. If all are well, the ignition switch would be the most likely culprit.
