Probably connected to your other post.

Have you changed the fuel filter lately? Do you know if your lift pump is working?

 

check for code p0341 camshaft position sensor, mine went out at 53k

 

So did mine. But on a 1999, I believe they used a CRANKshaft position sensor. I agree that this is probably your problem though.

 

its got a code p0336 ckp?

 

P0336 Crankshaft Position Sensor Performance.

You can find it here: http://www.dodgeram.org/tech/dsl/mt_...l_sys_comp.htm

 

I had to replace mine, but I was lucky because the Check Engine Light came on and I had the code read by a buddy with a scanner. It took about an hour after finding the correct tools. The starter bolts can be a BEAR to break loose, but it was an easy job.
