Stalling out other day it just died?

Hello,

I have a a 2001 Winnebago Rialta built on the 2001 engine, chassis, and drivetrain of the Volkswagen Eurovan.

I was driving the other day it just died. No warning or attempted stalling it just turned off.

Unfortunately this happened in the middle of an extremely busy intersection and I did not make many friends that day!

I sat in a turn lane and called AAA assuming I needed a tow. After about an hour of waiting for the tow truck. I tried starting the vehicle again and lo and behold it started back up much to my relief since I could now get it moving again. I called AAA and told them to put the service call on hold for now and I would let them know if I still needed the tow.

About 10 miles up the road it did the exact same thing but at least in a better spot where I could pull safely onto the shoulder. I thought I would wait to call AAA in case it was able to start again. I tried it again about 10 minutes later and it fired up again.

I started heading for home and it did it again but by now I realized just letting it sit for 10 minutes or so that it would start again. I texted a friend in the meantime who suggested removing the gas cap. I did and it started up and I got home safely, about 30 miles away.

I've left the gas cap off for a couple of days and it seemed to be ok. Over the weekend I put a brand new cap on it and changed the fuel filter to be on the safe side and headed out on a short road trip for my grandsons birthday. Everything was going great until it stalled again on a country road so at least I wasn't impeding traffic.

It started again 15 minutes later and did it once again about 10 more miles down the road.

I decided to take off the gas cap again even though I wasn't sure if this was a good idea or not but once it was off I got to my destination ok.

The next day I drove home with the cap still off and made it the entire 85 miles with no stalls.

I had codes checked at the local O'Reilly's and there were 3 codes.

P0740
P0725
P0441

The P0441 seemed to be the culprit but I haven't been able to find any info that it could actually cause the vehicle to stall and then recover awhile later.

Also twice on the journey there was a clunk sound that may have been from the transmission. It didn't affect me continuing to drive.

My apologies for the long question but you did say to be specific and give details! Ha!

If you could point me in the right direction on how to proceed it would be most helpful. While not a mechanic I have done some rudimentary repairs on my vehicles such as the fuel filter over the years and I'm hoping this might be a DIY situation to avoid an expensive trip to the dealer.

Thanks again!
