Toro Dingo Tx 427

I recently bought a used narrow track dingo, and had only put about 6 hours on it when it started doing a half-hearted power loss, then cut out. I restarted it it right away, and 3 cut-outs later had it in a safe place. I checked all the fluids. we had had three weeks of heavy rain, so did track thru muddy wet places. But no free-standing water and not bogged down in the mud. Just messy tracks.. I drained the gas to see if water in it. Don't see. The fuel filter was dirty and I changed it....
