Transmission shifts into reverse but stalls out when shifted into drive?

I haven't had any issues with the used van I have had for 20,000 miles. Now at just under 190,000. All was fine today after 4 hours plus of total driving (2 hours one way. 4 hours there, 2 hours back). No issues with the van. Get to a roundabout and suddenly the van stalls out as I get to a stop just before the roundabout. Put into park. Starts right up and idles just fine. Put I to drive and it stalls out with a little lurch as I hit the gas this time. Third time starts fine. Goes into reverse and goes fine. Shift the transmission into drive and it stalls out. Started it again and revved the engine to a point I got it revved enough to stay running with a lurching start to get it home.

I waited an hour I went back outside, it started just fine, and idled fine. Shifts into reverse fine but shifts into drive and it shuts off.

Please help!
