I'd be considering vapor lock too.  That's when the fuel  in the line gets
interrupted by a bubble of fuel fuel vapor caused by heat.  It's not
supposed to happen in injected engines due to high fuel pressure and the
constant return to the tank of hot fuel to be replaced by cool, but I
wouldn't rule it out.    The test would be for appropriate fuel pressure at
the injectors.

Try a different brand of gas too.  Maybe your stll getting the "winter mix"
with a lower vaporization pressure.

Subject: tiico stalling when hot

> Over the last couple weeks, my van (with a tiico engine) has died about
half a dozen times. Its only done it after driving for at least an hour,
leading me to believe its something temperature related. Once it dies, It
cranks over fine, but no start. Then, after about five minutes, it starts
right up, and will run for a while (the longer it sits, the longer it runs).
The temperature gage never rises above where it is normally. No unusual
fault codes on the vag-com. Replaced the fuel filter, and checked the lines
in the engine compartment, doesn't seem like thats the probelm. On short
trips, you'd never know anything was wrong.

when I put the engine in. yeah, I know, check for spark when it won't start.
haven't done that, only 'cause i've been by myself each time its happened.
any other ideas?
