I'm on vacation far from home. 

If weather above 70 f Chev Express usually starts on first crank.

Over 70 or van already warm immediately starts on 2nd crank.

Shows no codes.

Parts swappers previously replaced: Fuel pump twice ($1,200), Fuel line connectors ($250), Ignition Switch ($200), Checked fuses ($50), Battery ($200). $1850 total, no resolution.

This morning started driving, went into limp mode.  Seemed to run fine, just no throttle response.  As I backed it in parking lot started running rough.  Unfortunately I am 2,000 miles from home on vacation. Didn't bring my scan tool.

Now I'm a parts swapper.  I am thinking to swap out throttle position sensor, crank position sensor.  

Has anyone had this problem?
