Cuts off won't start back till cold
2001 ram1500 5.9....When cold truck starts right up.
Depending on the outside temperature how long it stays
running. Today was 8 1/2 minutes till it got up to normal
temperature and as soon as it does it cuts off and will not
start till cold again. Truck doesn't idle funny while running
nor right before it cuts off... new battery and fuel pump
installed about a month ago..
