Hi all, have a question. My 2001 ram 2500 van shuts off briefly and if i coast for 15 seconds i can turn key at it will start and then i may not have a problem again until i maybe drive on highway and get off and drive slow. This happens evry now and then, But sometimes when on highway it bucks briefly but doesn't shut off but i here a clicking from by the crankshaft position sensor or top of tranny. there are no codes andvan runs nice most of the time. What should i replace first? is coil going bad is tps going or crank p s or wires or cam p s or what. Any ideas. Thanks for any help

 

The PCM or the crank sensor in on it's way out.
